Thermally induced domain wall motion in a magnetic insulator was observed using spatiotemporally resolved polar magneto-optical Kerr effect microscopy. The following results were found: (i) the moves towards hot regime; (ii) threshold temperature gradient (5 K/mm), i.e., minimal required to induce motion; (iii) finite velocity outside of region with gradient, slowly decreasing as function distance, which is interpreted result from penetration magnonic current into constant region; and (iv)...

Relaxor ferroelectric polymers exhibit both high dielectric constants and low remnant polarization thus deliver much higher energy densities greater charge–discharge efficiencies than normal ferroelectrics for capacitive storage applications. Herein, behavior of several newly discovered relaxor is studied from a molecular perspective. It observed that the homopolymers very slim polarization–electric field loops highest among polymers, which are attributed to highly disordered chain...
Mixed ionic-electronic conducting (MIEC) thermoelectric (TE) materials offer higher ionic conductivity and Seebeck coefficient compared to those of purely ionic-conducting TE materials. These characteristics make them suitable for direct use in generators (TEGs) as the charge carriers can be effectively transported from one electrode other via external circuit. In present study, MIEC hydrogels are fabricated chemical cross-linking polyacrylamide (PAAM) polydopamine (PDA) form a double...
