Abstract
In the present paper, the effect of temperature on the shape of magnetic hysteresis loops for a magnetocaloric composite core was studied. The composite core, based on La(Fe, Mn, Si)13-H, was set up using three component disks with different Curie temperatures. The magnetic properties of the components and the outcome composite core were determined using a self-developed measurement setup. For the description of hysteresis loops, the phenomenological T(x) model was used. The presented methodology might be useful for the designers of magnetic active regenerators.

Summary
One of the most intriguing phenomena examined during studies on energy conversion is hysteresis. As already ultimate goal of the paper is to of the dependencies [18], canaccount be mentioned that the wide use ofrange a reliable hysteresis model ison more considered description takingitinto in a reasonably the effect of temperature the flexible, since loss dissipated as heat may always be obtained by integration of the loop area [19]. On the possibletemperature-dependent applications of AMRs hysteresis in magnetic refrigeration systems have recently in the Modeling loops might provide a better insight intobeen the issue of spotlight of the scientific community because of both the environmental burden caused by energy dissipation for temperatures close to the Curie point, and it might be useful for the design conventional solutions and the increasing energy consumption [31,32,33]
