Abstract

While Y₃Ni₇B₂ exhibits Pauli paramagnetism, ferromagnetic-like (T_c=36 K) behavior is observed in Y₃Ni₇B₂C. At 5 K and 50 kOe, the magnetization is M_s=0.04 μ_B/Ni. Above T_c, P_eff=0.9 μ_B/Ni. The P_eff/M_s ratio is characteristic of itinerant magnetism. Mössbauer studies at 4.2 K of doped ⁵⁷Fe indicate that the Ni in superconducting YNi₂B₂C is not magnetic. Thus, the ferromagnetic μSR signal found in RNi₂B₂C stems from an impurity phase of R₃Ni₇B₂C.
