AbstractAbstract
[en] An extensive survey of misinterpretations and misconceptions concerning presentation of the hysteresis loop for ferromagnetic materials occurring in undergraduate textbooks has recently been carried out. As a follow-up, this article provides similar examples, now drawn from recent magnetism literature. The distinction between the two notions of 'coercivity' referred to the B vs. H curve and the M vs. H curve, which turn out to be often confused in textbooks is elucidated. Various misinterpretations and conceptual problems revealed by our survey of recent magnetism-related scientific journals are summarized. In order to counteract the misinterpretations in question, some real examples of hysteresis loops showing the correct characteristics have also been identified in this search. Various ways of presenting units for the same physical quantity, i.e. the SI or cgs units as well as both units mixed, have been revealed in the regular articles. This is a worrying factor, which calls for a concerted action at the level of the whole magnetism community. A number of intricacies and fundamental conceptual problems in magnetism encountered in a recent review are dealt with in a separate note
