Kiecana, A. (author), Schaefers, W. (author), Thijs, M. (author), Dankelman, B.J.R. (author), Ojiyed, H. (author), Batashev, I. (author), Zhang, F. (author), van Dijk, N.H. (author), Brück, E.H. (author)Structural, magnetic and magnetocaloric properties of Mn<sub>3</sub>Sn<sub>1-</sub><sub>x</sub>Zn<sub>x</sub>C antiperovskite carbides have been studied. With increasing Zn content the first-order magnetic transition (FOMT) is weakened. The Curie temperature (T<sub>C</sub>) reduces first from 273 to 197 K and when x > 0.3, T<sub>C</sub>...journal article 2023

Kiecana, A. (author), Kwakernaak, C. (author), van Dijk, N.H. (author), Brück, E.H. (author)The effect of the heat treatment on the magnetism, magnetocaloric effect and microstructure formation has been systematically studied in Fe-rich (Mn,Fe)<sub>y</sub>(P,Si) melt-spun ribbons (1.80 ≤ y ≤ 2.00). XRD, SEM and EDS measurements demonstrate that a metal deficiency prompts the stable (Mn,Fe)Si phase, whereas in the metal-rich region...journal article 2023

(author)The effect of Co and Ni doping on the structure, magnetic and magnetocaloric properties of Fe-rich (Mn,Fe)<sub>2</sub>(P,Si) compounds was studied. With increasing Co and Ni content, both the Curie temperature (T<sub>c</sub>) and the thermal hysteresis (ΔT<sub>hys</sub>) decreased, whereas the hexagonal P-62 m crystal structure was maintained...journal article 2022

Lai, J. (author), You, X. (author), Law, Jiayan (author), Franco, Victorino (author), Huang, B. (author), Bessas, Dimitrios (author), Maschek, M. (author), Zeng, Dechang (author), van Dijk, N.H. (author), Brück, E.H. (author)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 Mn1-x2Vx2Fe0.95P0.563Si0.36B0.077 compounds enable a significant reduction in the thermal hysteresis without losing the giant...journal article 2022

(author)While rare-earth magnets exhibit unchallenged hard-magnetic properties, looking for alternatives based on inexpensive elements of non-critical supply remains of utmost interest. Here, we demonstrate that (Fe,Co)<sub>2</sub>(P,Si) single crystals combine a large magnetocrystalline anisotropy (K<sub>1</sub> ≈ 0.9 MJ m<sup>−3</sup> at 300 K),...journal article 2021

(author), Brück, E.H. (author)Approaching the border of the first order transition and second order transition is significant to optimize the giant magnetocaloric materials performance. The influence of vanadium substitution in the Mn<sub>1.2-x</sub>V<sub>x</sub>Fe<sub>0.75</sub>P<sub>0.5</sub>Si<sub>0.5</sub> alloys is investigated for annealing temperatures of 1323,...journal article 2019
