Direct magnetocaloric measurements of Fe-B-Cr-X (X = La, Ce) amorphous ribbons
(American Institute of Physics, 2011)
A procedure has been developed to directly measure the adiabatic temperature change of amorphous melt-spun Fe-based ribbons displaying attractive room temperature magnetocaloric properties. Polycrystalline Gd ribbons are ...

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 ...

Modification of the order of the magnetic phase transition in cobaltites without changing their crystal space group
(Elsevier, 2019-03)
It has been found that GdBa1-xSrxCo2O6-δ can exhibit consecutive magnetic transitions: antiferromagnetic-ferromagnetic (AFM-FM) transition followed by ferromagnetic-paramagnetic transition (FM-PM), which give rise to a ...

Enhancing the magnetocaloric response of high-entropy metallic-glass by microstructural control
(Springer, 2022)
Non-equiatomic high-entropy alloys (HEAs), the second-generation multi-phase HEAs, have been recently reported with outstanding properties that surpass the typical limits of conventional alloys and/or the first-generation ...
