Magnetic Properties of Highly Dispersed Ferromagnetics Obtained by the Thermochemical Method

The magnetic properties of highly dispersed powders of iron and iron compositions with silver, platinum, gold, copper, and zinc, obtained by the thermochemical method, are studied. Highly dispersed ferromagnetics are in the class of hard magnetic materials with a particle size of 0.02-0.20 µm. Hence, they fall into the category of single-domain or quasi-single-domain formations. These powders, which have now been produced for the first time, can be used in surgery, endocrinology, oncology, and other fields.
