The heat capacity of gadolinium has been measured over the temperature range 15 to 355°K. An enhanced heat capacity associated with the ferromagnetic transition was observed, with maximum at 18.6°C. The thermodynamic functions were computed and are tabulated for various temperatures. The results are discussed in connection with theories of ferromagnetism.
