Abstract

The magnetic and superconducting properties in the single crystals of (Y,Er)_1-xTb_xNi₂B₂C compounds were investigated by temperature-dependent magnetization M(T) and in-plane resistivity ρ_ab(T). It was found that the superconducting transition temperature T_c was suppressed by adding Tb in the sites of Y or Er and it follows well de Gennes scaling for both T_c > T_N and T_c < T_N. The antiferromagnetic T _N and weak ferromagnetic T_WF transition temperatures showed distinct behaviors in terms of the de Gennes (dG) factor in Y _1-xTb_xNi₂B₂C and Er _1-xTb_xNi₂B₂C. These observations were discussed under the consideration of magnetic ground states of ErNi ₂B₂C, TbNi₂B₂C and their interactions.
