Instabilities coarsening and chaos in driven systems : Growing interfaces and sheared wormlike micelles
We now provide a summary and outlook of the various topics discussed in this thesis. This thesis deals with systems driven far from equilibrium. Such systems show many interesting phenomena, notably nonequilibrium phase ... -
Interaction of hydrogen isotopes with radiation effects in metals
The present work has highlighted the deuterium behaviour during implantation in Cu, Ti and Pd, particularly relating to its migration, trapping and deuteride formation. The technique of neutron?yield measurement during ... -
Interfacial - Dzyaloshinskii - Moriya interaction in quasi-perpendicularly magnetized Ta/Pt/CoFeB/Pt ultra-thin films
The physics of Ferromagnetic-Metal/Heavy-Metal(FM/HM) ultra-thin film heterostructures is not only rich enough to investigate the interplay of magnetic interactions but also relevant enough to harness a new paradigm of ... -
Interfacial engineering to reduce switching current in perpendicularly magnetized Pt/Co/Pt system for memory applications
Tuning the interfacial properties of heavy metal (HM)/ Ferromagnet (FM)/ heavy metal (HM) thin film systems with perpendicular magnetic anisotropy (PMA) has attracted massive attention in the recent past because of their ... -
Interplay of disorder and superconductivity in ultra-thin Sn films
This thesis reports low-temperature, in-situ transport measurements on quench-condensed ultra-thin films of Sn. Film thicknesses are < 100 Å. These films exhibit an insulator-to-superconductor transition. Novel effects are ... -
Interplay of Electrons and Phonons in 2D Materials
