抄録

In order to study the magnetism in RRh₃B₂ (R=La, Ce, Nd, Sm, Eu and Gd), ¹¹B NMR has been measured systematically. LaRh₃B₂ was shown to be simply paramagnetic in the normal state, and GdRh₃B₂ and NdRh₃B₂ ferromagnetic with the well localized moments. In CeRh₃B₂, the K–χ plot and 1⁄T₁ can be interpreted in a localized moment model with a large reduction in the effective moment, and a small magnetic moment is considered to be localized at the Ce site below T_c. For SmRh₃B₂, 1⁄T₁ cannot be explained by the localized moment model, and it was found that the antiferromagnetic spin fluctuation exists in the paramagnetic state. The temperature dependence of 1⁄T₁T indicates that EuRh₃B₂ is a weak antiferromagnet.
