Abstract
The quaternary compound ErNi2B2C becomes superconducting with a critical temperature of 9 K. DC magnetisation indicates the presence of magnetic ordering of the Er moments at ≈ K. Specific heat measurements show a Schottky anomaly around 45 K with a magnitude of 10 J mol K-1 which agrees well with our model for the crystal-field scheme and neutron scattering data. We observed changes in the widths and positions of peaks in the crystal-field spectra, indicating the build up of magnetic interactions with the f electrons and thus contributing to the crystal-field Hamiltonian.
