IMAGING OF (MULTI)FERROIC SYSTEMS
We use optical imaging to study multilayered systems composed of magnetic and piezoelectric/ferroelectric layers. The objective is to achieve dynamical modulation of magnetization with electric fields. We also aim at the study of plasmon propagation along magnetic/ferroelectric interfaces, with the goal of achieving external control of the plasmon propagation with external fields.
Magneto-optical study of magnetoelectrics
Intrinsic interface magnetoelectric coupling mechanisms unveiled by magneto-optical analysis of Co/PZT heterostructures (O. Vlasin et al., ACS Appl. Mater. Interfaces, 8, 7553 (2016) DOI: 10.1021/acsami.5b12777). Coll. with Dr. S. Chérifi, CNRS-Univ. of Strasbourg, France
Local electro-optical responses
Our electro-optical imaging study of BaTiO3 thin films has revealed unexpected variations of the ferroelectric properties on the scale of the micron (O. Vlasin et al., Sci. Rep. 5, 15800 (2015)) DOI:10.1038/srep15800
