The current Special Issue of Minerals entitled “New Mineral Species and Their Crystal Structures” contains articles with full descriptions of recently discovered mineral species (verneite, thermaerogenite, parafiniukite, nöggerathite-(Ce), cerromojonite, aurihydrargyrumite, sharyginite, fiemmeite, oyonite, tiberiobardiite, and ariegilatite) and with recent results in the investigation of structures for minerals which were insufficiently studied in the crystal chemical aspect (rusinovite, barioferrite, kurchatovite, and clinokurchatovite). The described new minerals demonstrate a great chemical and structural diversity and are characterized by different formation conditions and mineral associations. The mineralogical discoveries come from many different localities around the world. All articles were prepared to a high scientific level, and the authors used a lot of modern methods for their investigation of the solid. The papers published in this Special Issue can be of interest not only to mineralogists and mineral collectors but also to physicists and chemists of solid, and specialists in the field of materials science.

Hematite (à-Fe2O3), the stable oxide of iron, is a major constituent of soils, rocks and the earth's crust. It has unique magnetic properties that make it the prototype for the class of materials known as canted antiferromagnets.This book has no equivalent. The mean-field theory is treated in detail, and thus the book is a useful text for students mastering this general method. Information obtained by a wide variety of experimental methods is provided. These techniques include x-ray and neutron diffraction; electron magnetic resonance; M”ssbauer spectroscopy; and thermal, optical, electrical and elastic measurements.

By illustrating a wide range of specific applications in all major industries, this work broadens the coverage of X-ray diffraction beyond basic tenets, research and academic principles. The book serves as a guide to solving problems faced everyday in the laboratory, and offers a review of the current theory and practice of X-ray diffraction, major advances and potential uses.
