Abstract
Microscopic coexistence between weak ferromagnetism (WFM) and superconductivity (SC) in Tb0.47Y0.53Ni211B2C was investigated. Magnetization measurements indicate that antiferromagnetic (AFM), WFM and SC transitions occur in this material. Unpolarized neutron diffraction experiments revealed that the AFM order is best described by a longitudinal spin density wave with a propagation vector of q=0.550a∗. Polarized neutron diffraction experiments further confirmed that the WFM order is originated in Tb0.47Y0.53Ni211B2C.
