About awarded research:

E M K Ikball Ahamed, Md Shamim Sarker, Hiroyasu Yamahara and Hitoshi Tabata, “Spin wave modulation by strain induced remanent polarization in functional Iron Oxide thin films,” International conference on complex orders in condensed matter: aperiodic order, local order, electronic order, hidden order held on 24-29 September 2023 at Evian, France.

Rare-earth Iron Garnets (RIG) have gained technological interest due to their potential applications in spintronic and magnonic devices. The presence of strain gradient induces a remanent dielectric polarization in RIG thin films. Symmetry broken YIG films by controlling epitaxial strain are needed to achieve this property. This study aims to facilitate strain induced electrical polarization in the functional oxide thin films. Magnetization of RIG thin-films can be modulated by strain induced electric polarization with the application of electric field according to the magnetoelectric effect. Using comb-shaped interdigital metal electrodes, we investigate the in-plane polarization characteristics of epitaxially strained RIG thin films and electric field-controlled spin wave propagation.
