Phonon Anomalies And Phase Transitions In Pyrochlore Titanates, Boron Nitride Nanotubes And Multiferroic BiFeO3 : Temperature- And Pressure-Dependent Raman Studies
This thesis presents experimental and related theoretical studies of pyrochlore titanate oxides, boron nitride nanotubes, and multiferroic bismuth ferrite. We have investigated these systems at high pressures and at low ...
Probing Magnetic And Structural Properties Of Metallic Nanowires Using Resistivity Noise
The main focus of this thesis work has been the study of domain wall (DW) dynamics in disordered cylindrical nanomagnets. The study attempts to accurately quantify the stochasticity associated with driven (temperature/magnetic ...
