ANALYSIS OF SPECIFIC HEATS OF CERIUM, NEODYMIUM, AND SAMARIUM AT HIGH TEMPERATURES

OSTI ID:4787043
The specific heats at constant pressure of cerium, neodymium, and samarium in the paramagnetic state were analyzed in terms of lattice, electronic, and dilatation conibutions. Electronic contribution is made up of two parts: specific heat due to the localized 4f-electrons and the usual electronic specific heat of conduction electrons. The exexperimental curves of temperature vs heat capacity at constant pressure can be fitted to the theoretical predictions reasonably well for cerium and only approximately for neodymium from 300 up to 800 deg K. This is not, however, possible for samarium. (auth)
