IEEE transactions on applied superconductivity, 2022 It is expected to build a sustainable social system that uses “hydrogen” as a fuel to generate electricity without emitting CO2. To realize this, technology for storing a large amount of hydrogen is indispensable, and storage as liquid hydrogen is ideal.

Effect of Dy substitution in the giant magnetocaloric properties of HoB$_{2}$
, 2020 Recently, a massive magnetocaloric effect near the liquefaction temperature of hydrogen has been reported in the ferromagnetic material HoB$_{2}$. Here we investigate the effects of Dy substitution in the magnetocaloric properties of Ho$_{1-x}$Dy$_{x}$B ...

Magnetocaloric Effect of Two Gd-Based Frameworks
Inorganics, 2022 Magnetic refrigeration material is the key to adiabatic demagnetization refrigeration technology. In this work, two magnetic refrigerants, Gd5(C4O4)(HCOO)3(CO3)2(OH)6·2.5H2O (1) and Gd2(OH)4SO4 (2), were prepared through hydrothermal reaction.

Magnetic refrigeration down to 1.6 K for the future circular collider e^{+}e^{-}
Physical Review Accelerators and Beams, 2017 High-field superconducting rf cavities of the future circular collider e^{+}e^{-} may require a kW-range superfluid helium refrigeration down to 1.6 K. Magnetic refrigeration operating below 4.2 K can be an alternative to the compression/expansion helium

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.

Cold production from magnetic fields. Part II: Thermodynamic analysis
Revista Facultad de Ingeniería Universidad de Antioquia, 2003 In magnetic refrigeration a magnetic material undergoes temperature changes or heat interchanges with the environment when it is placed in a strong magnetic field. In this paper, a conventional cycle for magnetic refrigeration is analyzed.
