A New High‐Pressure Polymorph of MgTe2O5 with a Unique Crystal Structure

European Journal of Inorganic Chemistry, EarlyView.
MgTe2O5 synthesized under special high‐pressure/high‐temperature conditions of 8 GPa and 800 °C exhibits a unique crystal structure consisting of fused sechser rings built from pseudooctahedral [TeO5]6– and trigonal‐pyramidal [TeO3]2– units. The single‐crystal structure and temperature‐dependent powder diffraction data are presented.

Reconfigurable Giant Nonreciprocity at Near‐Normal Incidence via Phase‐Change Magneto‐Optical Metagratings

Laser &Photonics Reviews, EarlyView.
A phase‐change magneto‐optical metagrating combines GST switching with InAs guided‐mode resonances to achieve strong nonreciprocal absorption contrast near normal incidence. A static magnetic bias creates direction‐dependent resonant splitting, while GST crystallization quenches and latches the response.
