RESEARCH INTEREST:

Magnetic multilayers
(i) The role of various parameters characterizing the state of interface like interdiffusion, correlated and un-corelated interfacial roughnesses and in-plane height-height correlation length on the magnetic interactions in systems with (a) Perpendicular magnetic anisotropy (PMA), viz. Fe/Tb (b) Giant magnetoresistance (GMR), viz. Fe/Cr.
For details: Interface structure variation on PMA and GMR

(ii) The structure of epitaxial Cr/Sn multilayers

(iii) Correlation of structure and magnetotransport in Co/Cu multilayers, pseudo and exchanged biased spin valves and TMR structures.
