| dc.description.abstract | This thesis presents experimental as well as theoretical studies on several contemporary
systems like quantum spin liquids (QSLs), skyrmion lattices, and transition metal dichalcogenides
(TMDs) under extreme conditions like low temperature (down to 4K) and ultra high
pressures (up to 26 GPa). Temperature-dependent Raman studies are carried out to investigate
Raman signatures of Kitaev quantum spin liquid (QSL) state of Cu2IrO3 and Ag3LiIr2O6 and
orbital ordering in Heisenberg quantum magnet Ca10Cr7O28. High-pressure studies are performed
on Kitaev QSL candidates -RuCl3, Cu2IrO3, kagomé QSL ZnCu3(OH)6Cl2, skyrmion
lattice system Cu2OSeO3, and TMD candidate VSe2. Structural and vibrational evolutions of
these systems under pressure are probed by X-ray diffraction measurements using synchrotron
source and Raman scattering, respectively. | en_US |
