Zhang, F. (author), Smits, Sebastian (author), Kiecana, A. (author), Batashev, I. (author), Shen, Q. (author), van Dijk, N.H. (author), Brück, E.H. (author)The influence of doping with the 5d transition metal W has been studied in the quaternary (Mn,Fe)<sub>2</sub>(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 temperature T<sub>C</sub> and retain the thermal...journal article 2023

Shen, Q. (author), Zhang, F. (author), Dugulan, A.I. (author), van Dijk, N.H. (author), Brück, E.H. (author)In this work, the magnetocaloric effect and negative thermal expansion in melt-spun Fe<sub>2</sub>Hf<sub>0.83</sub>Ta<sub>0.17</sub> Laves phase alloys were studied. Compared to arc-melted alloys, which undergo a first-order magnetoelastic transition from the ferromagnetic to the antiferromagnetic phase, melt-spun alloys exhibit a second...journal article 2023

Shen, Q. (author), Batashev, I. (author), Zhang, F. (author), Ojiyed, Hamutu (author), Dugulan, A.I. (author), van Dijk, N.H. (author), Brück, E.H. (author)The transition-metal based Laves phase materials represent an extended family of alloys with rich and fascinating physical properties. In this work, we have investigated the negative thermal expansion and magnetocaloric effect in arc-melted and melt-spun Fe<sub>2</sub>Hf<sub>1-</sub><sub>x</sub>Ti<sub>x</sub> (x = 0.15, 0.27, 0.30, 0.33, 0.36...journal article 2023

(author), Brück, E.H. (author)In the field of nanoscale magnetocaloric materials, novel concepts like micro-refrigerators, thermal switches, microfluidic pumps, energy harvesting devices and biomedical applications have been proposed. However, reports on nanoscale (Mn,Fe)<sub>2</sub>(P,Si)-based materials, which are one of the most promising bulk materials for solid-state...journal article 2022

Shen, Q. (author), Batashev, I. (author), Ojiyed, Hamutu (author), Zhang, F. (author), van Dijk, N.H. (author), Brück, E.H. (author)The influence of excess Mn on the magnetoelastic ferromagnetic-to-antiferromagnetic transition T<sub>t</sub> in the magnetocaloric compound (Mn,Cr)<sub>2</sub>Sb has been studied. With increasing excess Mn the magnetoelastic transition temperature for (Mn,Cr)<sub>2</sub>Sb initially increases and then decreases. This trend is accompanied by a...journal article 2022
