¹¹B Nuclear Spin-Lattice Relaxation in Itinerant Weak Antiferromagnetic SmRh₃B₂

Abstract

¹¹B nuclear spin-lattice relaxation time T₁ has been measured in order to study the anomalous properties of SmRh₃B₂ from the microscopic viewpoint. No anomaly has appeared at the temperature where the electric resistivity changes drastically. The temperature dependence of 1⁄T₁T in the paramagnetic state (T>100 K), where the uniform magnetic susceptibility hardly changes with temperature, has been found to show the typical weak antiferromagnetic case of itinerant electrons.
