【 摘 要 】

We synthesized single crystals of an itinerant ferromagnet LaCo2P2 with ThCr2Si2-type structure and studied their magnetism by magnetization and P-31 NMR measurements. We measured Knight shift K and spin-lattice relaxation rate divided by temperature 1/T1T with the applied fields parallel to the a and c axes, and estimated spin fluctuations in the ab plane and c. In addition, we evaluated spin fluctuations from the result of magnetization data with a three-dimensional ferromagnetic model. There is little anisotropy in evaluated spin fluctuations in the ab plane and c. Spin fluctuations of LaCo2P2 have a three-dimensional character and can be understood in the framework of the self-consistent renormalization theory of spin fluctuations.
