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 ...

Additive manufacturing of magnetocaloric (La,Ce)(Fe,Mn,Si)13–H particles via polymer-based composite filaments
(Elsevier, 2022-11)
Additive manufacturing could be an excellent way of shaping magnetocaloric heat exchangers in magnetic refrigerators. However, the metal additive manufacturing techniques present the serious limitation that the melting of ...

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 ...

Ultra-low Hysteresis in Giant Magnetocaloric Mn1-xVxFe0.95(P,Si,B) Compounds
(Elsevier, 2023)
Large thermal hysteresis in the (Mn,Fe)2(P,Si) system hinders an efficient heat exchange and thus limits the magnetocaloric applications. Substitution of manganese by vanadium in the Mn1-x1Vx1Fe0.95P0.593Si0.33B0.077 and ...

Excellent Cryogenic Magnetocaloric Properties in Heavy Rare-earth Based HRENiGa2 (HRE = Dy, Ho, or Er) Compounds
(Science Press, 2023)
RENiX2 compounds, where RE = rare-earth element and X = p-block element, have been highly regarded for cryogenic magnetocaloric applications. Depending on the elements, they can crystallize in CeNiSi2-type, NdNiGa2-type, ...

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 ...
