“…In fact, the crossing of hysteresis branches has been referred to as being energetically incorrect and nonphysical 2 , and a problem 3 with the SW-model. A number of authors have proposed other models or modifications to the SW-model in order to eliminate the “problem” of crossover 13 – 15 . It is unclear why many researchers have assumed that HBC is non-physical.…”

The Stoner–Wohlfarth model predicts the crossing of the ascending and descending branches of the hysteretic magnetization curve. This crossing behavior has widely been dismissed, with the claim that it violates the laws of thermodynamics. Experimental verification of hysteresis branch crossing has not been acknowledged in the literature. Here we show, both theoretically and experimentally, that the crossing of the ascending and descending branches of the magnetization curve is a robust, reproducible phenomenon which does not violate any fundamental law.
