(author)Magnetocaloric materials undergoing reversible phase transitions are highly desirable for magnetic refrigeration applications. (Mn,Fe)<sub>2</sub>(P,Si) alloys exhibit a giant magnetocaloric effect accompanied by a magnetoelastic transition, while the noticeable irreversibility causes drastic degradation of the magnetocaloric properties...journal article 2022

(author), Sebastiano, F. (author), Vandersypen, L.M.K. (author)One of the main bottlenecks in the pursuit of a large-scale-chip-based quantum computer is the large number of control signals needed to operate qubit systems. As system sizes scale up, the number of terminals required to connect to off-chip control electronics quickly becomes unmanageable. Here, we discuss a quantum-dot spin-qubit...journal article 2022

(author)In view of the interest that (Fe,Co)<sub>2</sub>(P,Si) compounds have as potential permanent magnets, their structural and magnetic phase diagrams are explored focusing on establishing the range where the hexagonal Fe<sub>2</sub>P-type structure is observed. In Fe<sub>1.93-x</sub>Co<sub>x</sub>P<sub>1-y</sub>Si<sub>y</sub>, the highest Si...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)We performed neutron-diffraction experiments and density functional theory calculations to study the magnetostructural coupling in MnCoGeBx (x=0, 0.01, and 0.05) alloys. By varying the amount of boron addition, we are able to freely switch the magnetostructural coupling on and off in the MnCoGe alloys. It is found that the boron addition...journal article 2020

(author), Brück, E.H. (author)Ni-Mn-X (X = In, Sn, and Sb) based Heusler alloys show a strong potential for magnetic refrigeration owing to their large magnetocaloric effect (MCE) associated with first-order magnetostructural transition. However, the irreversibility of the MCE under low field change of 0–1 T directly hinders its application as an efficient magnetic coolant....journal article 2019
