properties. Chapter 2 summarizes data on crystal structure and includes comparisons with III–V and II–VI semiconductors. The next chapter presents phase diagrams and properties of practical importance such as specific heat, Debye temperature, thermal expansion, and thermal conductivity, again comparing other semiconductors. The data on elastic constants, hardness, and lattice dynamic properties, covered in chapter 4, are useful to have in one place. The next chapter on band structure combines theory with empirical correlations of energy gap with molecular weight and effective cubic lattice constant. The chapter on optical properties is relevant to solar cells and optoelectronic applications. The final chapter on carrier transport properties includes discussions on electron and hole Hall mobilities and conduction mechanisms.

his book presents some recent advancements in the area of magnetic perovskites and gives an introduction to the physics of complex magnetism (phase separation, spin glass, frustration). It is written from a materials science perspective and is essentially based upon scientific publications from the author. Thus, it only contains the results of a few recently studied compounds and may need to be updated in the future. Nevertheless, it can serve as an introduction to students starting in the field of magnetic perovskites. The book is organized into four chapters. Chapter 1 briefly introduces the materials. After describing the importance of perovskites and a description of the structure, the author presents the synthesis. It is, however, restricted to single-crystal cobaltites; it is surprising that the author does not even mention thin-film growth techniques despite the huge amount of work in that
area, as well as the potential applications in oxide electronics. The chapter ends with a list of key properties reported, corresponding only to those detailed in the book. Chapter 2 presents results of electronic phase separation and glassy behavior. The first example is manganites, A1–xBxMnO3 (A = La, Pr, Nd, Gd, and Y and B = Ca, Ba, Sr), which exhibit electronic phase separation. An example of glassy behavior in A0.7Ba0.3MnO3 (A = La, Nd, and Gd) is also given. The second example is a cobalt-centered perovskite that displays electronic phase and spin-glass behavior. Chapter 3 discusses the A-site cationic ordering and disordering effects on magnetotransport properties of cobaltites. This section starts with a clear description of ordered and disordered perovskites. The description of disordered ABO3 perovskites was not necessary, and this content could have been
A special feature is the attention devoted to material parameters—stoichiometry, alloying, doping, grain boundaries, graded structures—and heat treatment. There are 26 categories of solar cells, including those made of earth-abundant materials, ranging in efficiency from 10.6% to 46
