The novel all-d-metal Ni(Co)MnTi based magnetic Heusler alloys provide an adjustable giant magnetocaloric effect and good mechanical properties. We report that the second-order magnetic phase transition can be tailored in this all-d-metal NiCoMnTi based Heusler system by optim ...
The effect of Co and Ni doping on the structure, magnetic and magnetocaloric properties of Fe-rich (Mn,Fe)2(P,Si) compounds was studied. With increasing Co and Ni content, both the Curie temperature (Tc) and the thermal hysteresis (ΔThys) decreased, whereas the hexagonal P-62 m c

The influence of doping with the 5d transition metal W has been studied in the quaternary (Mn,Fe)2(P,Si) based giant magnetocaloric compounds, which is one of the most promising systems for magnetic refrigeration. It is found that W substitution can separately decrease the Curie

The growing demand for energy highlights the need for developing more efficient and environmentally friendly technologies. Magnetic cooling based on the magnetocaloric effect is a promising alternative for compressor-based refrigeration. Among various magnetocaloric materials, Mn

Structural, magnetic and magnetocaloric properties of Mn3Sn1-xZnxC antiperovskite carbides have been studied. With increasing Zn content the first-order magnetic transition (FOMT) is weakened. The Curie temperature (TC) reduces first from 273 to 197 K and when x > 0.3, TC increas

The effect of the heat treatment on the magnetism, magnetocaloric effect and microstructure formation has been systematically studied in Fe-rich (Mn,Fe)y(P,Si) melt-spun ribbons (1.80 ≤ y ≤ 2.00). XRD, SEM and EDS measurements demonstrate that a metal deficiency pro ...

The substitution of Mn by Ni in (Mn,Fe)2(P,Si) compounds and its magnetocaloric consequences
A comparison with research studies on cobalt regarding tuneable curie temperature, hysteresis and magnetization
With green energy well on its way to becoming a necessity rather than a commodity it is vital to not only focus on improving the source of energy, but also the efficiency of the eventual energy usage. Vapor-compression based household refrigerators are one of the most used electr
