Further Investigations on Magnetic Properties of Co(SxSe1-x)2, (0≤x≤1)

摘要: Further investigations, succeeding to the works of J. Phys. Soc. Japan 26 (1969) 631 and 29 (1970) 323, on magnetic properties Co(S x Se 1- ) 2 in whole concentration ranges (0≤ ≤1) were performed by means high field, electrical resistivity low temperature X-ray diffraction measurements. The first kind transition was found ferromagnetic phase except CoS . metamagnetic behaviors observed (0.89< <1.0) as well paramagnetic ( <0.89) phases. saturation moment per Co atom obtained be 0.855 µ B for it decreased gradually with increasing content. temperatures showed a T -dependence. It concluded that itinerant electron model base spin fluctuation theory is more adequate than models based localized scheme.
