N2 - While Y3Ni7B2 exhibits Pauli paramagnetism, ferromagnetic-like (Tc=36 K) behavior is observed in Y3Ni7B2C. At 5 K and 50 kOe, the magnetization is Ms=0.04 μB/Ni. Above Tc, Peff=0.9 μB/Ni. The Peff/Ms 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.
