Altermagnetic perovskites

npj Spintronics
Altermagnet is a class of antiferromagnets, which shows a staggered spin ordering with wave vector ${\bm q}=0$, while its net magnetization is canceled out in the limit of zero relativistic spin-orbit coupling. The simplest case is when the up and down spins are ordered on two crystallographically equivalent sublattice sites within the unit cell that ...

Electronic spin state of ferric iron in Al-bearing perovskite in the lower mantle

, 2005
We investigate the effect of pressure on the electronic spin state of ferric iron on Al-bearing MgSiO3-perovskite using first-principle computations. Ferric iron (6.25 mol%) and Al ( 6.25 mol%) substitute for Mg and Si respectively.

Perovskite-Sensitized Upconversion under Operando Conditions

, 2023
Perovskite-sensitized upconversion (UC) has resulted in near-infrared-to-visible UC at solar-relevant fluxes. However, the successful implementation of UC devices into operating solar cells will result in exposure to similar environmental stressors as ...
