Response of periodic systems to electromagnetic fields: multipole expansion, microscopic charge-current density, polarization and magnetization
Polarization and magnetization fields are central concepts in the theory of light-matter interaction, because they describe the distribution of charges and currents induced in the material medium due to an application of electromagnetic fields. Here I develop strategies to treat polarization and …

Theory of Electronic Response to Electromagnetic Fields in Crystalline Solids
… interactions, the introduction of macroscopic polarization and magnetization fields, and free charge and current densities, provides physical insight into the distribution and the dynamics of the charges that constitute a material medium. Here we consider a semi-classical theory of such …

Induced Phase Transition in Magnetoelectric BiFeO3 Crystals, Thin-layers and Ceramics
… which exhibits simultaneously ferroelectric and antiferromagnetic properties. We have used high-field electron spin resonance (ESR) as a local probe of the magnetic order in the magnetic range of 0-25 Tesla. With increasing magnetic field, an induced transition has been found between …

Magnetoelectric laminated composites and devices
… found in laminated composites of piezoelectric and magnetostrictive layers. Compared to ME single phase and two phase particulate composites, laminated composites have much higher ME coefficients and are also readily fabricated. In this thesis, I have investigated ME effect in laminated …
