This series of books, which is published at the rate of about one per
year, addresses fundamental problems in materials science. The contents
cover a broad range of topics from small clusters of atoms to
engineering materials and involves chemistry, physics, materials science
and engineering, with length scales ranging from Ångstroms up to
millimeters. The emphasis is on basic science rather than on
applications. Each book focuses on a single area of current interest and
brings together leading experts to give an up to date discussion of
their work and the work of others. Each article contains enough
references that the interested reader can access the relevant
literature. Thanks are given to the Center for Fundamental Materials
Research at Michigan State University for supporting this series. M. F.
Thorpe, Series Editor E mail: thorpe@pa. msu. edu V PREFACE This book
records invited lectures given at the workshop on Physics of Manganites,
held at Michigan State University, July 26 29, 1998. Doped manganites
are an interesting class of compounds that show both metal insulator and
ferromagnetic to paramagnetic transitions at the same temperature. This
was discovered in the early 1950s by Jonker and van Santen and basic
theoretical ideas were developed by Zener (1951), Anderson and Hasegawa
(1955), and deGennes (1960) to explain these transitions and related
interesting observations.
