Magnetic properties of RNi4B (R=Y, Gd) : magnetic and specific-heat measurement

YNi4B is a paramagnetic compound with the susceptibility equal to 2.7×10−6 emu/g at 5 K. From the low-temperature specific heat, values of 458 K for the Debye temperature and 14.1 mJ/K2 mol for the coefficient of the electronic specific heat are obtained. GdNi4B is ferromagnetic below Tc=35.0 K wher...

Zusammenfassung:	YNi4B is a paramagnetic compound with the susceptibility equal to 2.7×10−6 emu/g at 5 K. From the low-temperature specific heat, values of 458 K for the Debye temperature and 14.1 mJ/K2 mol for the coefficient of the electronic specific heat are obtained. GdNi4B is ferromagnetic below Tc=35.0 K where the λ-type anomaly is observed in the specific heat. Magnetic and specific-heat measurements provide strong evidence that the 3d band in YNi4B and GdNi4B is completely filled.
