Group-9 Transition Metal Suboxides Adopting the Filled-TiNi Structure: A Class of Superconductors Exhibiting Exceptionally High Upper Critical Fields
KeYuan Ma, Robin Lefèvre, Karolina Gornicka +5
The TiNi and the related -carbide structure are known to exhibit various intriguing physical properties. The TiNi structure with the cubic space group is su…
Synthetic control over polymorph formation in the d-band semiconductor system FeS
KeYuan Ma, Robin Lefèvre, Qingtian Li +4
Pyrite, also known as fool's gold is the thermodynamic stable polymorph of FeS. It is widely considered as a promising d-band semiconductor for various applications due to its…
A Heavy-Fermion Zn-deficient CaBe2Ge2-Type Phase with Rare Ce-based Ferromagnetism and Large Magnetoresistance
Robin Lefèvre, Fabian O von Rohr
We report on the hitherto unknown compound CeZn2-dGe2 (d approx 0.41). We find this compound to crystallize in a defect version of the well-known CaBe2Ge2 structure type. The phase…
Superconductivity with High Upper Critical Field in the Cubic Centrosymmetric -Carbide NbRhC
KeYuan Ma, Karolina Gornicka, Robin Lefevre +5
The upper critical field is a fundamental measure of the strength of superconductivity in a material. It is also a cornerstone for the realization of superconducting magnet applica…
