The NATO Science Series continues the series of books published formerly as the NATO ASI Series.
The NATO Science Programme offers support for collaboration in civil science between scientists of
countries of the Euro-Atlantic Partnership Council. The types of scientific meeting generally supported
are "Advanced Study Institutes" and "Advanced Research Workshops", although other types of
meeting are supported from time to time. The NATO Science Series collects together the results of
these meetings. The meetings are co-organized bij scientists from NATO countries and scientists from
NATO's Partner countries - countries of the CIS and Central and Eastern Europe.
Advanced Study Institutes are high-level tutorial courses offering in-depth study of latest advances
ina field.
Advanced Research Workshops are expert meetings aimed at critical assessment of a field, and
identification of directions for future action.
As a consequence of the restructuring of the NATO Science Programme in 1999, the NATO Science
Series has been re-organised and there are currently Five Sub-series as noted above. Please consult
the following web sites for information on previous volumes published in the Series, as wellas details of
earlier Sub-series.

PREFACE
Advanced materials of today's technology deserve thorough knowledge of their
preparation and properties. They must be studied on an atomic and/or subatomic scale.
Mossbauer spectroscopy is a well-established and rapidly evolving analytical tool,
which provides superior possibilities via its different variations to probe the nearest
atomic neighbourhood of the resonant spy atoms both from the structural and also from
the hyperfine interaction point of view. The diagnostic potential of Mossbauer effect is
underlined by its application in a variety of fields of human activities.
Mossbauer spectroscopy offers a unique possibility for hyperfine interaction studies
via probing the short-range order of resonant atoms. Materials, which contain the
respective isotope as one of their constituent elements (e.g., iron, tin, ... ), but also those
which even do not contain them, can be investigated. In the latter case, the probe atoms
are incorporated into the material of interest in minor quantities (ca. 0.1 at. %) to act as
probes on a nuclear level.
This workshop has covered the topics evolving most recently in the field of
Mossbauer spectroscopy applied to materials science. During five days, 49 participants
from 19 countries discussed the following areas: Nanoscale Systems, Conversion
Electron Mossbauer Spectroscopy, Magnetism, Nanocrystalline Alloys and Metals,
Synchrotron Radiation, Minerals, and New Developments. A total of 42 contributions
(34 keynote and 8 contributing speeches) reviewed the current state of the art of the
method, its applications for technical purposes, as well as trends and perspectives.
A total of 35 papers are included in the present volume. In the chapter Nanoscale
Systems, two main ways of preparation of fine particles were discussed, namely via
mechanosynthesis and thermal processing. Their characterization was done primarily by
Mossbauer effect techniques but in combination with complementary methods.
Conversion Electron Mossbauer Spectroscopy offers a possibility to trace the
surface layers down to the depth of about 150 nm, thus extending the diagnostic
potential of the method. The application of this technique to the study of modified steel
surfaces as well as surfaces of nanocrystalline alloys and organic thin films was
reviewed with a special emphasis on the basic principles of the method.
Mossbauer spectroscopy is an analytical tool, which provides both structural and
magnetic information about the system under investigation. The latter feature was
treated in a special section devoted to Magnetism. The advantages of the use of external
magnetic fields in these studies were pointed out and combined with the infonnation
from classical magnetic measurements.
Recently, nanocrystalline materials, which show outstanding features for practical
technological applications, have emerged. Investigations dealing with their magnetic and
structural properties are discussed in the section Nanocrystalline Alloys and Metals. It is
shown that structurally different atomic positions can be identified in nanocrystalline
multiphase systems. Non-conventional processing of steels and their characterization by
the help of other techniques completes this chapter.
A fundamentally different approach to the use of the nuclear resonance is
demonstrated in the chapter entitled Synchrotron Radiation. Basic principles and
applications of nuclear resonance scattering of synchrotron radiation with high temporal
IX
x
and spatial resolution for the study of diffusion processes and magnetic properties are
described there.
For thousands of years, minerals have been of great importance for mankind.
Examples of applicability of Mossbauer effect studies are presented in Chapter VI,
Minerals, for mineral magnetism and oxidation processes.
The potential of Mossbauer diffraction, emission Mossbauer spectroscopy, and
Mossbauer polarimetry prove the ongoing expansion of this technique in new directions.
Chapter VII, New Developments, summarises the contributions related to the topics
mentioned before as well as the new concepts of data evaluation of complex Mossbauer
spectra. An unusual application of the Mossbauer effect in dosimetry finalises this
chapter and the whole proceedings.
This NATO Advance Research Workshop continues the tradition of a series of
scientific conferences devoted to material research entitled Mossbauer Spectroscopy in
Materials Science (msms). Starting in 1994, the meetings are held on a biannual basis
in Slovakia and the Czech Republic in Kocovce (1994), Lednice (1996), Senec (1998),
Velke Losiny (2000), and Smolenice (2002). The aims of a msms are always to
contribute to the critical assessment of the existing knowledge on new important topics,
to identify directions for future research, and to promote close working relations among
scientists from different countries and with different professional experience. This year,
the funding was provided by NATO to cover organizational expenses, travel and living
expenses of keynote speakers and to contribute to travel and living expenses of other
participants 40% to 50% of whom are from Partner or Mediterranean Dialogue
countries. In our opinion, these aims have really been achieved during this stimulating
conference. All the participants agreed and supported the idea that this conference series
should certainly be continued. In this respect, we gratefully acknowledge the financial
support of the NATO Scientific Committee that made such an event and also these
proceedings possible.
We would also like to express our deepest gratitude to all the participants for the
energy and efforts they put into making this workshop and proceedings very successful.
