Abstract
It is shown that magnetic anisotropy induced in certain ferrimagnetic materials by thermomagnetic treatment can store information on the temeperature of thermal treatment and the strength of a magnetic field in which it was performed. It is also shown that a ferrimagnetic material can “memorize” several temperatures and field strengths of a few magnetic fields (both constant and variable).
