Ni-Based Alloys for Magnetic Hyperthermia: Comparison of Direct and Indirect Methods for Determining Magnetocaloric Parameters

This work describes experimental study by a direct and indirect method of magnetocaloric properties of Ni-based alloys: Ni 93.8 V 6.2 , Ni 89.5 Al 10.5 , Ni 72.5 Cu 27.8 , which are promising materials for self adjusting magnetic hyperthermia. It has been demonstrated that the temperature of the maximum magnetocaloric effect determined by these methods can differ significantly, which is of critical importance for self-adjusting hyperthermia.
