文摘

Magnetic and electrical properties of new ternary compounds RInNi₄ with R=Ce, Pr and Tm have been investigated. The magnetic susceptibility χ and the electrical resistivity ρ show the absence of magnetic order in these systems down to 2K at low fields. χ of CeInNi₄ indicates that the Ce ion is close to Ce⁴⁺ state. For PrInNi₄, while χ at the field of H=0.1T shows a characteristic behavior of a nonmagnetic ground state due to a crystal field splitting, the magnetization M for H≥0.75T reveals the presence of a ferromagnetic transition at T_cg align=center border=0 SRC=/images/glyphs/BQ1.GIF>3K. Moreover, the M vs. H for T≤4K exhibits a metamagnetic transition at H_cg align=center border=0 SRC=/images/glyphs/BQ1.GIF>1T. It is suggested that a significant mixing of the crystal field levels is relevant to the field-induced transition in PrInNi₄.
