Outline of Final Research Achievements

Spinel and Heusler compounds with spin-glass freezing were investigated by means of thermodynamically. Ferri-magnetism FeCr2S4 has an orbital-ordered (OO) phase. The magnetic new phase induced by magnetic field was found out in the OO phase. The enhancement of the spin-freezing temperature by applying pressure was observed. This enhancement might due to the increasing of the strength of the magnetic frustration came from the spinel-crystal structure. For Heusler Ru2-xFexCrSi, the concentration x dependence of the density of states for the majority- and minority-spin band at Fermi level was determined using the results of specific heat and Andreev-refraction measurements.
