説明
The nuclear magnetic relaxation of 59Co in dilute Cr1−xVxCo (x\lesssim0.05) and Cr1−xMoxCo (x\lesssim0.25) alloys in the ordered state was investigated. T1 is proportional to 1⁄T in the region of T<<TN. T1T decreases rapidly with the decrease of the ordering temperature associated with the increase of x. This decrease of T1T with the decrease of the ordering temperature is generally observed in randomly ordered systems in metals irrespective of the ferro and antiferromagnet. Approximate model calculations based on the Weger mechanism, where the nuclear Zeeman energy relaxes to the kinetic energy of the conduction electrons via the virtual excitation of the spin waves, have been carried out in PdCo, whose T1 was already measured, and in CrVCo alloys. The experimental results are explained qualitatively well by the Weger mechanism.
