The magnetic susceptibility of CsCl-type CoTi was expressed as the Curie-Weiss susceptibility plus temperature independent term at temperatures above about 300 K, i.e. 1637⁄(T+6.66)+3.92 in the unit of 10−4 emu/mol. In the same temperature range, the d spin component of the relaxation rate associated with the 59Co nuclei showed saturation from the low temperature Korringa process. From the analysis of the d-spin relaxation, it is concluded that the amplitudes of the temperature dependent spin density fluctuations are saturated above T*=300 K and behave as if local moments are induced.
