Setting the basis for the interpretation of temperature first order reversal curve (TFORC) distributions of magnetocaloric materials
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)
First Order Reversal Curve (FORC) distributions of magnetic materials are a well-known tool to extract information about hysteresis sources and magnetic interactions, or to fingerprint them. Recently, a temperature variant ...

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 ...

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 ...

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 ...

Analysis of the magnetic field dependence of the isothermal entropy change of inverse magnetocaloric materials
(Elsevier, 2021)
In this work, the magnetic field dependence of the inverse magnetocaloric (MC) effect is analyzed using a mean field approach for describing antiferromagnetic to ferromagnetic magnetoelastic transitions. The model is able ...

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 ...
