説明
Magnetic properties and electrical conductivity of the YFe2O4 single crystal were investigated. It was disclosed that YFe2O4 is an antiferromagnet whose Néel point is 205 K, and the spin lies parallel to the hexagonal c axis. Below TN, the magnetization parallel to the c axis was not proportional to the magnetic field. A large rotational hysteresis was observed at temperatures between 170 and 120 K. Below 140 K, a weak but very hard ferromagnetic moment parallel to the c axis resulted from field cooling. On the basis of these facts, a model of parasitic ferromagnetism, i.e., preferential location of Fe2+ and Fe3+ ions on each antiferromagnetic sublattice, is proposed. If such a preferential location is caused by the difference of the exchange interaction constant, YFe2O4 is the first example of an annealed random spin system.
