Interpretation of hysteresis loops of cobalt-rare-earth single particles

The magnetic behavior of single particles of Co

Sm is being studied in an effort to understand the origin of the coercive force in cobalt rare earths. It has been found that the complex hysteresis loops often observed, containing several magnetization discontinuities, can be analyzed as the linear sum of single-discontinuity hysteresis loops, implying that regions of a particle can act magnetically independently.
