Specific heat data on the new quaternary magnetic superconductor ErNi2
B2C is presented in the temperature range 20-300K. Crystalline Electri
c Feild Effects (CEF) are confirmed by the existence of a Schottky ano
maly around 45K with a magnitude of 10 Jmol(-1)K(-1). The Schottky pea
k is analysed in terms of a CEF levels scheme based on neutron data.
