Tuning thermo-magnetic properties of dilute-ferromagnet multilayers using RKKY interaction

, 2020
We demonstrate a 20-fold enhancement in the strength of the RKKY interlayer exchange in dilute-ferromagnet/normal-metal multilayers by incorporating ultrathin Fe layers at the interfaces.

Magnetocaloric effect in bamboo-grained Ni-Mn-Ga microwires over a wide working temperature interval

Materials & Design, 2020
Bamboo-grained Ni-Mn-Ga microwire is promising for achieving considerable magnetic-field-induced strain due to less neighboring grain constraints to the twin boundary motion.

Suppression of the thermal hysteresis in magnetocaloric MnAs thin film by highly charged ion bombardment

, 2014
We present the investigation on the modifications of structural and magnetic properties of MnAs thin film epitaxially grown on GaAs induced by slow highly charged ions bombardment under well-controlled conditions.

Active magnetic regenerative refrigeration using superconducting solenoid for hydrogen liquefaction

Applied Physics Express, 2022
A magnetic refrigerator that makes use of the magneto-caloric effect realizes a highly efficient cooling device. Since the cooling power of magnetic refrigerators depends largely on the strength of the magnetic field, the use of a superconducting magnet ...

Magnetocaloric effect in manganites: metamagnetic transitions for magnetic refrigeration [PDF]

, 2010
We present a study of the magnetocaloric effect in La5/8-yPryCa3/8MnO3 (y=0.3) and Pr0.5Ca0.09Sr0.41MnO3 manganites. The low temperature state of both ystems is the result of a competition between the antiferromagnetic and ferromagnetic phases.
