Influence of shape of a specimen is questioned by computational modeling. A new mesoscopical-level model modifying the conventional micromagnetics in a suitable way is used. Numerical simulations made for uniaxial ferromagnets as, e.g., CoZrDy demonstrate explicit dependence of the hysteretic response on the geometry of the specimen.
