Al substitution effect on magnetic properties of magnetocaloric material HoB2

Suguru Iwasaki et al.

Summary: The Al substitution effect on HoB2's Curie temperature (T-C) was investigated. EDS analysis showed that Al substitution led to inhomogeneous elemental distribution, resulting in segregation into HoB2 and B-substituted HoAl2. The results indicated that Al substitution did not alter T-C1 but varied T-C2. Stoichiometric HoB2 mainly contributed to the maximum value of the magnetic entropy change (|delta S-M|) at T-C1.

Magnetocaloric effect near room temperature and critical behaviour of Fe doped MnCo0.7Fe0.3Ge

Sateesh Pinninti et al.

Summary: This study focused on the critical magnetic behavior, universality class, and magnetocaloric properties of Mn0.7Fe0.3Co0.7Fe0.3Ge alloy. The alloy was found to crystallize in the hexagonal structure and exhibit paramagnetic to ferromagnetic phase transition at around 298K. Short range magnetic interactions with 3D-Heisenberg universality class were inferred from the critical exponents. Around the Curie temperature, the alloy showed a significant change in magnetic entropy under the influence of 90 kOe.
