We performed 75As-NMR measurements to investigate the normal-state magnetic properties of CeRh2As2, a recently-discovered heavy-fermion superconductor. The magnitude and temperature dependence of the Knight shift at the As(2) site indicate easy-plane-type magnetic anisotropy in CeRh2As2. With regard to spin fluctuations, the temperature dependence of the nuclear spin-lattice relaxation rate 1/T1 arising from the 4 f electrons decreases from high-temperature constant behavior on cooling at ∼40 K, which is a typical behavior of heavy-fermion systems. In addition, 1/T1 becomes constant at low temperatures, suggesting spatially two-dimensional antiferromagnetic fluctuations.
