ABSTRACT:
A method and the instrument associated therewith for determining the Curie points of ferromagnetic materials which display no significant abrupt change in heat absorption around the Curie points thereof by means of a conventional thermal analyzer with externally added facilities to provided an external magnetic field. The abrupt change of heat absorption of the ferromagnetic materials is increased by adding the external magnetic field to increase the magnetic anisotropy energy thereof and to strengthen the spontaneous magnetization thereof.
