Novel spin, charge, and lattice dynamics in pyrochlore iridates : Raman and X-ray diffraction studies at low temperatures and high pressure

Rosalin, M

This thesis investigates phonon dynamics, electronic, and spin excitations along with structural instabilities and phase transitions in rare earth pyrochlore iridates, A2Ir2O7 (A = Pr, Gd, Dy, and Er) and Bi-doped Sm2Ir2O7 ...
Structure–Property Correlation in the Lead-Free K0.5Bi0.5TiO3-Based Piezoceramics

Punetha, Pooja

Ferroelectric materials with a perovskite (ABO₃) structure exhibiting enhanced electromechanical properties are widely used in actuators, pressure sensors, electro-optic devices, and transducers across sectors such as ...
