Thermodynamic, magnetic and electrical properties of the Nd7Co6Al7 intermetallic phase have been extensively studied. The compound crystallises in the tetragonal Pr7Co6Al7 type structure (space group P4/mbm) and undergoes a ferromagnetic transition at 15.5 K. From the hysteresis loop the values of the remanence and of the coercive field were obtained. Magnetic heat capacity measurements allow to obtain the magnetocaloric effect related to the magnetic transition. An estimate of refrigerant capacity of the compound is obtained.

Abstract
Thermodynamic, magnetic and electrical properties of the Nd7Co6Al7 intermetallic phase have been extensively studied. The compound crystallises in the tetragonal Pr7Co6Al7 type structure (space group P4/mbm) and undergoes a ferromagnetic transition at 15.5 K. From the hysteresis loop the values of the remanence and of the coercive field were obtained. Magnetic heat capacity measurements allow to obtain the magnetocaloric effect related to the magnetic transition. An estimate of refrigerant capacity of the compound is obtained.
