Strain-Induced Relaxor Multiferroicity at Room Temperature in Hexaferrite BaFe12O19 Thin Films

Yilin Evan Li, Harikrishnan KP, Sankalpa Hazra +19

Multiferroic materials that combine magnetic and electric order at room temperature are rare. Here, we demonstrate strain-induced room-temperature polar order in the ferrimagnetic…

Microscopic mechanisms of flexoelectricity in oxide membranes

Harikrishnan KP, Varun Harbola, Jaehong Choi +9

Modern electromechanical actuators and sensors rely on the piezoelectric effect that linearly couples strain and electric polarization. However, this effect is restricted to materi…

Improper Ferroelectricity at the Monolayer Limit

Yilin Evan Li, Harikrishnan KP, Haidong Lu +20

Ultrathin ferroelectric films with out-of-plane polarization and high Curie temperatures are key to miniaturizing electronic devices. Most ferroelectrics employed in devices are pr…

Electron ptychography reveals a ferroelectricity dominated by anion displacements

Harikrishnan KP, Ruijuan Xu, Kinnary Patel +9

Sodium niobate, a lead-free ferroic material, hosts delicately-balanced, competing order parameters, including ferroelectric states that can be stabilized by epitaxial strain. Here…
