This paper is devoted to study of physical processes occurring in weak ferromagnetics iron -borate doped diamagnetic magnesium under external influence. The ideas of phase transitions are not only successfully applied in various fields of modern physics, but also in biology, chemistry, geology, and even economics and other social sciences. Thus, the article presents the results of the study of changes in the magnetic properties of iron borate when a magnesium mixture is added and the properties of this change as a result of external influences (temperature, mechanical impact, magnetic field and light). |
