Giant rotating magnetocaloric effect enhanced by crystal electric field in antiferromagnetic ErNi3Al9 single crystal

Effect of magnetocrystalline anisotropy on magnetocaloric properties of AlFe$_{2}$B$_{2}$ compound

“…6,7 The application of magnetocrystalline anisotropy is the rotating magnetocaloric effect. [8][9][10][11][12][13][14] The temperature and heat exchange of the anisotropic magnetic material can be controlled by rotating the sample (or changing the relative direction of the external magnetic field) at a fixed strength of the applied magnetic field. The origin of this effect is the modification of the magnetocrystalline anisotropy on the magnetization when changing the relative direction of the external magnetic field.…”

“…However, several experimental studies have found that the isothermal magnetic entropy change is modified not only on the low-temperature side but also on the high-temperature side of the main peak when a magnetic field is applied in different directions. [8][9][10][11][12][13][14] The magnetocrystalline anisotropy energy affects the isothermal magnetic entropy change even above the Curie temperature in the anisotropic magnetocaloric effect.…”
