Method of temperature Curie determination of ferromagnetic metals and alloys in industrial laboratory

摘要

The thermodynamic substantiation of simple and convenient method of Curie temperature (as one of the major characteristics of ferromagnetic metals and alloys) determination in conditions of modern industrial laboratory is given. Calculated dependences of magnetization and susceptibility are determined by solution of the cubic thermodynamic equation of ferromagnetic state. Comparison of theoretical results with experimental data for a precision Ni_(36)Fe_(64) alloy is carried out. High accuracy of the offered approach is shown.
