Due to their non-centrosymmetric structure, B20-type compounds have intriguing properties of chiral magnets and are the objects of study of topological spin textures. Among them is a high-pressure phase MnGe, which demonstrates properties of magnetic

Herein, we report on intermetallic iron germanide (Fe6Ge5) as a novel oxygen evolution reaction (OER) precatalyst with a Tafel slope of 32 mV dec−1 and an overpotential of 272 mV at 100 mA cm−2 in alkaline media. Furthermore, we uncover the in si

Fe32+δGe33As2 and Fe32+δ′Ge35−xPx are quasi-binary intermetallic compounds that possess a rare variant of intergrowth-type crystal structure, which is a combination of the column shaped Co2Al5 and MgFe6Ge6 structure type blocks. The compounds a

The Fe-Ge system resides among the richest binary intermetallic systems both in terms of the number of intermediate phases and diversity of crystal structures and magnetic properties. Although crystal structures of the Fe-Ge binary phases are differe
