Problems of construction of rather inexpensive vibrating sample magnetometer available in manufacturing and its uses for measurement of magnetic parameters of ferromagnetic alloys as well as the analysis of phase transformations into them in a wide range of temperatures are considered. Designing principles, circuits’ decisions and parameters of the wide-range magnetometer for the magnetic phase analysis of alloys are given. The magnetometer allows observing a wide range of the processes during dynamics, which are accompanied by change of magnetization of studied object. High characteristics of the magnetometer are reached due to signal transformation by a method of synchronous detecting. Efficiency of use of the magnetometer is confirmed with results of pilot studies of cast alloys for permanent magnets on the base of Fe-Ni-Al-Co, deformable hard magnetic Fe-Cr-Co alloys, a number of constructional materials and their blankets after different types of superficial processing, amorphous magnetic materials, and magnetic suspensions on the liquid-metals’ base.
Keywords: magnetometer vibrational, saturation magnetization, high-coercivity materials, amorphous magnetic materials, laser surface treatment.
