CoTe2: A quantum critical Dirac metal with strong spin fluctuations
Peter E. Siegfried, Hari Bhandari, Jeanie Qi +13
Quantum critical points separating weak ferromagnetic and paramagnetic phases trigger many novel phenomena. Dynamical spin fluctuations not only suppress the long-range order, but…
Origin of spin reorientation and intrinsic anomalous Hall effect in the kagome ferrimagnet TbMn6Sn6
D. Connor Jones, Suvadip Das, Hari Bhandari +6
TbMnSn has attracted a lot of recent interest for a variety of reasons, most importantly, because of the hypothesis that it may support quantum-limit Chern topological magn…
Room-temperature ferrimagnetism of anti-site-disordered Ca2MnOsO6
Hai L. Feng, Madhav Prasad Ghimire, Zhiwei Hu +18
Room-temperature ferrimagnetism was discovered for the anti-site-disordered perovskite Ca2MnOsO6 with Tc = 305 K. Ca2MnOsO6 crystallizes into an orthorhombic structure with a space…
Ba2NiOsO6: A Dirac-Mott insulator with ferromagnetism near 100 K
Hai L. Feng, Stuart Calder, Madhav Prasad Ghimire +14
The ferromagnetic semiconductor Ba2NiOsO6 (Tmag ~100 K) was synthesized at 6 GPa and 1500 °C. It crystallizes into a double perovskite structure [Fm-3m; a = 8.0428(1) Å], where the…
