Combined kinetic and Bean–Rodbell approach for describing field-induced transitions in LaFe11.6Si1.4 alloys
(Institute of Physics Publishing, 2021)
We propose a combination of the Kolmogorov–Johnson–Mehl–Avrami nucleation and growth theory and the Bean–Rodbell model to describe the field-induced transition in LaFe11.6Si1.4 alloys. The approach is applied to a set of ...

Increased magnetocaloric response of FeMnNiGeSi high-entropy alloys
(Elsevier, 2021)
The search for high-entropy alloys (HEAs), a new class of materials, with high magnetocaloric perfor- mance can address the open question about their potential in functional applications. HEAs exist in a vast compositional ...

Reversibility of the Magnetocaloric Effect in the Bean-Rodbell Model
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
The applicability of magnetocaloric materials is limited by irreversibility. In this work, we evaluate the reversible magnetocaloric response associated with magnetoelastic transitions in the framework of the Bean-Rodbell ...

Obtaining magnetocaloric MnCo(Fe)Ge intermetallics from low temperature treatment of mechanically alloyed precursors
(Elsevier, 2020)
Production of the intermetallic MnCo0.8Fe0.2Ge phase, interesting as magnetocaloric material, is obtained by using an almost fully amorphous mechanically alloyed precursor. Thermal treatment to develop the intermetallic ...

First- and second-order phase transitions in RE6Co2Ga (RE = Ho, Dy or Gd) cryogenic magnetocaloric materials
(Science in China Press, 2021)
Rare-earth (RE) rich intermetallics crystallizing in orthorhombic Ho6Co2Ga-type crystal structure exhibit peculiar magnetic properties that are not widely reported for their magnetic ordering, order of magnetic phase ...

Design of Fe-containing GdTbCoAl high-entropy-metallic-glass composite microwires with tunable Curie temperatures and enhanced cooling efficiency
(Elsevier, 2021)
Through designing the composition and processing approach, the non-equiatomic (Gd36Tb20Co20Al24)100-xFex (x = 0, 1, 2 and 3 at.%) high-entropy-metallic-glass (HE-MG) alloy microwires were successfully fabricated by ...

Milling effects on the distribution of Curie temperatures and magnetic properties of Ni-doped La0·7Ca0·3MnO3 compounds
(Elsevier, 2020)
A systematic study of the magnetic and magnetocaloric properties around the ferromagnetic-paramagnetic phase transition temperature have been carried out on La0.7Ca0.3Mn1-xNixO3 (x = 0, 0.02, 0.07, 0.10) compounds ...
