A New Method for Determining the Curie Temperature From Magnetocaloric Measurements
(Institute of Electrical and Electronics Engineers, 2016)
A new method is proposed for determining the Curie temperature from magnetocaloric measurements. It is based on the field dependence of the magnetic entropy change close to the Curie temperature. The main advantages over ...

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 ...

Effect of α-Fe impurities on the field dependence of magnetocaloric response in LaFe11.5Si1.5
(Elsevier, 2015)
In this work, the theoretical field dependence of the magnetic entropy change far away from the transition is used to analyze the field dependence of composite materials formed by fcc La(Fe,Si)13 and bcc α-Fe(Si) phases. ...

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, ...

The role of Ni in modifying the order of the phase transition of La(Fe,Ni,Si)(13)
(Elsevier, 2018)
In this work, we study the effect of Ni substitution on the magnetocaloric properties of La(Fe,Si)13 compounds. Sample quality has been optimized by a combination of induction melting and suction casting techniques, which ...

Magnetocaloric response of amorphous and nanocrystalline Cr-containing Vitroperm-type alloys
(Elsevier, 2016)
The broad compositional range in which transition metal (TM) based amorphous alloys can be obtained, yields an easily tunable magnetocaloric effect (MCE) in a wide temperature range. In some TM-based alloys, anomalous ...

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 ...

Analysis of magnetocaloric effect of ball milled amorphous alloys: Demagnetizing factor and Curie temperature distribution
(Elsevier, 2015)
The magnetocaloric effect (MCE) has been measured for an amorphous mechanically alloyed (MA) Co62Nb6Zr2B30. It is demonstrated that sample shape must be taken into account for a correct interpretation of the results, ...

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 ...
