On the Magnetic Properties of Nickel-Arsenide Type Crystals

抄録

The formation of the ordered arrangement of the magnetic moments of cations (spin ordering or spin arrangement) in the crystal lattice of the nickel-arsenide type is studied theoretically with the molecular field approximation, taking into account interaction between pairs of cations, which form the first, second or third neighbours in the crystal lattice. Various types of spin arrangement in this structure with two kinds of cations are derived. Based on the results obtained the magnetic properties of the compounds are discussed. The theory is applied as a typical example to the interpretation of the magnetism of the ternary solid solution of manganese-chromium-antimony system.
