Magnetic Field and Pressure-Dependent Raman Spectroscopy

Quantum materials having interactions among various degrees of freedom (lattice, charge, spin, and orbital) exhibit properties that are fundamentally important and are promising for next generation device applications, such as, spintronics, quantum computing and many others. Tailoring such interactions may pave the way towards new emergent phenomena. Raman scattering is a process that can elucidate these interactions by probing various quasiparticles/excitations, e.g., phonons, magnons, orbitons, etc. This chapter highlights some aspects of Raman spectroscopy and its applications in the characterization of quantum materials with pressure and magnetic field as the tuning parameter/external perturbation. Such perturbations are responsible for modulating properties such as quantum phase transitions, multiferroicity, novel magnetic ground states, and several exotic phenomena. Finally, we will conclude this chapter with a discussion on the scope of such studies in materials analyses for a more comprehensive range of applications.
