(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

Yibole, H. (author), Lingling-Bao, B. (author), Xu, J. (author), Alata, H. (author), Tegus, O. (author), Hanggai, W. (author), van Dijk, N.H. (author), Brück, E.H. (author), Guillou, F. (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
