Minor Hysteresis Loops and Bloch Wall Potential in a Fe Single Crystal

摘要: The minor hysteresis loops were measured with increasing magnetic field amplitude, H a , step by and analyzed in connection the lattice defects such as dislocations Fe single crystal. We defined pseudo coercive force c * susceptibility χ at loss W F remanence B R work magnetization loop. is where becomes zero A simple relation, 2 = was experimentally obtained wide range. These parameters reflect Bloch wall potential on supposition that walls receive from same potential; average one of individual wall. initial stage concluded to be irreversible properties.
