Realistic first-principles calculations of the magnetocaloric effect: applications to hcp Gd

Figures & data

Figure 1. Temperature-dependent magnetization derived from MC simulations of hcp Gd using different statistical approaches. Temperature is normalized according to $T_C$ of the experimental (293 K) and calculated (315 K) data. Experimental data extracted from Ref. [25].

Figure 2. Temperature-dependent magnetic entropy variation from MC simulations using different statistics schemes. For a detailed description of the mixed scheme, see text.

Figure 3. Temperature-dependent electronic and lattice contributions for the entropy variation.

Figure 4. Variation of the total entropy change between the PM and FM configuration at a magnetic field change of 2 T. Temperature is normalized according to the entropy peak temperature of the experimental (291 K) and calculated (317 K) data. Experimental data from Ref. [6].
