Multiferroic and Magnetoelectric Oxides: The Emerging Scenario
, 2012 Multiferroics were considered to be rare because magnetism and ferroelectricity require entirely different criteria for the materials. Several multiferroic oxides have, however, been discovered in the past few years by virtue of novel operating ...

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks
Advanced Science, EarlyView.Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

Colossal Photovoltaic Current in Ferroelectric Oxide by Constructing Defect Band
Advanced Science, EarlyView.Colossal photovoltaic current density of 34.36 mA/cm2 under 375 nm illumination has been achieved in the Pb‐deficient PbTiO3 film. The ultraviolet photoresponsivity surpasses that of all reported ferroelectric materials. This enhancement is attributed to the junction effect between the Pb‐deficient and non‐defective layers.

Field‐Frustrated Cooperative Distortions: Suppressing Jahn‐Teller Ordering via Microwave Annealing
Advanced Science, EarlyView.Microwave annealing decouples local Jahn‐Teller distortions from long‐range cooperative ordering in CuFe2O4, stabilizing a metastable cubic phase that remains locally distorted yet globally symmetry‐frustrated. Synchrotron XRD, PDF, XPS, and in situ thermal cycling reveal how non‐equilibrium MW‐phonon interactions suppress cooperative orbital‐lattice ...
