Magnetic Properties of MM’X (M= Mn, M’= 3d or 4d Metal, X = P, As, Si, Ge) Compounds with Hexagonal or Orthorhombic Crystal Structure

Abstract

Abstract. In this review paper comparison of magnetic properties in several MM’X-type intermetallics is presented. It may be summarized that main role in variation of magnetic interactions is played by modification of metallic sublattice in the tetrahedral but not in the pyramidal sites. It was shown not only in the case of composition, temperature and magnetic field dependencies but also by pressure variation of magnetic interactions. The latter was confirmed especially by electronic band structure calculations. Finally, in this report spin component and orbital one of magnetic moments for CoMnGe is presented for the first time.
