Ferrimagnetism
-
Ferrimagnetic Materials
materials are ceramics, or ceramic oxides
-
-
this method provides a reliable way of forming a wide variety of shapes and size embedding into technological devices
Introduction
exhibit a spontaneous magnetic moment and hysteresis below the Curie temperature and behave paramagneticcally above Curie temperature
-
widely used in non-volatile memory devices, which utilize their ability to easily switch the spins of electrons and be magnetized
Temperature Dependence
similar to ferromagnetic materials, which the magnetic moments become randomized at Curie temperature and behave paramagnetically
the saturation magnetization of a ferrimagnetic materials decreases with increasing temperature until it vanishes at Curie temperature
magnetization decrease before Curie temperature and paramagnetic above the Curie temperature
