“V doping enhances Ti-O covalence and introduces mid-gap states, resulting in a reduced band gap and improved charge transfer.”

“Cr doping drives a transition to an A-type AFM phase that breaks Kramers spin degeneracy and realizes a g-wave altermagnetic state with large nonrelativistic spin splitting near the Fermi level. Importantly, this spin splitting can be deterministically reversed by polarization switching, enabling electric-field control of altermagnetic electronic structure without reorienting the Neel vector or relying on spin-orbit coupling.”

“The method presented here enables nearly 100% reversible trion-to-exciton conversion without the need of electrostatic gating, while delivering thermally stable trions with a large binding energy of ~56 meV and a high free electron density of ~3$ imes$10$^{13}$ cm$^{-2}$ at room temperature.”

“The study reveals a transformation from a 4a0 × 4a0 CDW order to a √7a0 × √3a0 ordering upon intercalation, associated with an insulating gap.”

“The substituted compound Gd$_{0.9}$Ce$_{0.1}$CrO$_3$ (GCCO) exhibits a remarkably large magnetic entropy change, $Δ$ S $\sim$ 45-40 J/kg-K for $Δ$ H = 90-70 kOe at 3 K among the highest reported for rare-earth orthochromites.”

“The research focuses on the van der Waals ferromagnet CrTe2 engineered by Nb doping.”
