Magnetic field induced dielectric relaxation in the strain glass state of Pr0.6Ca0.4MnO3

, 2013
We present the dielectric and magnetodielectric properties of Pr0.6Ca0.4MnO3 polycrystalline sample. Dielectric permittivity ({\epsilon'}) (and d{\epsilon'}/dT) portrays the charge order and other magnetic transitions observed in the magnetization ...

Optically Driven Dynamics of a Mott Insulator‐to‐Metal Transition

Advanced Functional Materials, Volume 35, Issue 10, March 4, 2025.
Photoinduced phase switching at the first‐order Mott insulator‐to‐metal transition in the 4d‐electron compound Ca3(Ru0.99Ti0.01)2O7 is triggered by specific Ru t2g d d interband transitions excited by light. The material's extraordinary photo‐sensitivity, with avalanche‐like propagation of phase interfaces across the entire macroscopic sample, arises ...

Radiative Warming Glass for High‐Latitude Cold Regions

Advanced Science, Volume 12, Issue 9, March 6, 2025.
In contrast to widely reported radiative cooling technologies, a radiative warming glass is proposed for high‐latitude cold regions, proving significant energy‐saving potential compared with commercial high‐performance low‐e glass. Abstract Traditional window glazing, with inherently adverse energy‐efficient optical properties, leads to colossal energy
