Abstract
A new method for the quantitative estimate of the phase composition of a multiphase ferromagnetic alloy is suggested that is based on measuring the temperature and field dependences of the magnetization. The phase composition of ultrafine Co-P powders is characterized. Phase diagrams of nonequilibrium Co-P solid solutions are constructed on particle size, i.e., the phosphorus concentration coordinates.
