Effect of temperature on magnetism pdf
WebThese temperature dependencies have also been experimentally observed in NiFe 2/5 Cr 8/5 O 4 and Li 1/2 Fe 5/4 Ce 5/4 O 4. A temperature lower than the Curie temperature, but at which the opposing magnetic moments are equal (resulting in a net magnetic moment of zero) is called a magnetization compensation point. This compensation point is ... WebSep 18, 2011 · The thermal effects were incorporated through temperature-dependent hysteresis parameters of the existing model, adding critical exponent and Curie temperature as additional parameters.
