Abstract
We studied zero-field (Formula presented) and (Formula presented) nuclear magnetic resonance (NMR) in (Formula presented) The (Formula presented) and (Formula presented) NMR intensities, resonance frequencies, and spin-spin relaxation times showed thermal hystereses upon cooling and warming. The analysis of the result shows that there are two distinct phase regions below (Formula presented) a stable metallic ferromagnetic (FM) region and a region where metallic FM and insulating antiferromagnetic phases compete. The two metallic FM phases are distinguished by mobile (Formula presented) electron density. The (Formula presented) electron density of the stable FM phase is 0.5, but that of the FM phase in the competition region is lower than that.
