Abstract

We report the results of 31P-nuclear magnetic resonance (NMR) measurements on the layered cobalt oxyphosphide Sr2Sc(Co1-xFe x )PO3 in order to investigate the magnetic properties at low temperatures from a microscopic view point. The 31P-Knight shifts measured at the resonance peak maximum of Sr2Sc(Co1-xFe x )PO3 have positive values and are T-independent in an entire temperature range, and the absolute value decreases with increasing Fe content. Also, the nuclear spin-lattice relaxation rate 1/T 1 is almost proportional to the temperature at low temperatures. The magnitude of 1/T 1 T decreases with increasing the Fe content, which suggests the decrease of the density of states around the Fermi level.
