Abstract
A phenomenon of mutual influence of the demagnetizing field and a gradual increase of width of minor loops in bulk ferromagnets during magnetization processes is scrutinized by computational modeling. Classical static micromagnetics is here enriched by a suitable activated dissipation mechanism allowing for rate-independent hysteresis. The activation threshold is allowed to depend, again by a rate-independent manner, on local history of a magnetization process, which reflects (only on a mesoscopical level) gradual development of a domain structure. Influence of the shape of the specimen is thus automatically involved via nonlocal interactions through the demagnetizing field.
