NMR Spectra of 59Co and 14N in CoN
Abstract
Nuclear magnetic resonance (NMR) measurements of 59Co and 14N in CoN with a zincblende type structure were carried out in the temperature range from 4.2 K to room temperature. NMR Spectra of 59Co are obtained from Free Induction Decay (FID) signals in a static field of 6.3068 T. NMR Spectra of 14N are obtained by spin-echo method in the same static field. The temperature variations of Knight shifts are derived from resonance peak positions at various temperatures. In this experiment, it is found that the temperature variations of Knight shifts are very small. Therefore, it is concluded that the compound CoN has Pauli paramagnetism. This is consistent with the result of the temperature-independent susceptibility.
