ABSTRACT:
Magnetic medium for storing information, includes at least two materials A and B which are connected with one another, material A being a hard magnetic material, wherein material B is a material which exhibits metamagnetic behavior in a magnetic field, the metamagnetic behavior of the material being such that, even after passing repeatedly through an external magnetic field from 0 to 10 tesla at least at a magnetic field strength below 3 tesla, an increase in the magnetization occurs as a function of the magnetic field, the increase being superproportional and having a positive curvature.
