Summary

Here, we investigated polycrystalline pseudo-binary (Ho,Er)Ni2 intermetallic compound. Its magnetic and thermodynamic properties were extensively studied over a wide field range, which enables to define and describe high-field regularities of magnetocaloric effect. The isothermal magnetic entropy change and relative cooling power were estimated based on magnetization measurements. The magnetocaloric parameters obtained for the temperatures from the phase transition range are discussed in the framework of the mean-field theory for the second-order phase transitions. Precise experimental characterization of the magnetic properties of the (Ho,Er)Ni2 intermetallic compound was also performed. Composite with optimum proportions of the individual parent and Ho0.5Er0.5Ni2 compounds were theoretically determined.
