TL;DR: In this paper, the magnetocaloric effect has been studied on polycrystalline Ho5Pd2 compound, which undergoes magnetic field-induced first order metamagnetic transition from antiferromagnetic to ferromagnetic state below antiferrous transition temperature.
Abstract: The study of magnetocaloric effect has been performed on polycrystalline Ho5Pd2 compound, which undergoes magnetic field-induced first order metamagnetic transition from antiferromagnetic to ferromagnetic state below antiferromagnetic transition temperature. A large magnetic entropy change associated with the field-induced metamagnetic transition has been observed over a wide temperature range. The evaluated value of relative cooling power is 6.32J∕cm3 for a magnetic field change of 5T, which is even larger than that for reported best known magnetic refrigerant materials irrespective of the temperature range.

4 × SE
7 solutions of D = 11 supergravity at finite temperature and charge density and in the presence of a magnetic field. We construct black hole solutions corresponding to the unbroken phase, and at zero temperature some of these become dyonic domain walls of an Einstein-Maxwell-pseudo-scalar theory interpolating between AdS
4 in the UV and new families of dyonic $ Ad{S_2}\times {{\mathbb{R}}^2} $
solutions in the IR. The black holes exhibit both diamagnetic and paramagnetic behaviour. We analyse superfluid and striped instabilities and show that for large enough values of the magnetic field the superfluid instability disappears while the striped instability remains. For larger values of the magnetic field there is also a first-order metamagnetic phase transition and at zero temperature these black hole solutions exhibit hyperscaling violation in the IR with dynamical exponent z = 3/2 and θ = −2.
