The compound Co2NbGa crystallizes in the Heusler-type structure. Magnetization measurements of Co2NbGa have been made under ambient pressure using a SQUID magnetometer. The spontaneous magnetic moment at 5 K and the Curie temperature are 1.81 μB/f.u. and 351 K, respectively. Many magnetic properties of the itinerant electron ferromagnets are explained by the Takahashi’s spin fluctuation theory. In the Takahashi’s spin fluctuation theory, spectral parameters of spin fluctuations,T0andTA, are involved in various magnetic properties derived theoretically. In this work, we estimatedT0andTAof Co2NbGa by using the results of magnetization measurements at 5 K:T0= 2.1 × 103K andTA= 4.7 × 103K. This experiment proved that the squared spontaneous magnetizationMs(T)2is proportional toT2at low temperature. TheTAvalue estimated from theMs(T)2vs.T2curve is 6.6 × 103K. Furthermore, the field-induced magnetizationM4aroundTCis found to be proportional toH/Min the low magnetic field region.
