Spin dynamics with the interplay of elasticity and radiation in hybrid systems

Originated from the electron’s intrinsic angular momentum, magnetism has endowed various manipulations in both macroscopic and microscopic setups with another degree of freedom. Beyond the traditionally developed usage such as storage and sensors, there are enormous applications based on engineering and integrating magnetism into heterostructures and their susceptibility to external stimuli. The emergent fields of nano-level spintronics and spin caloritronics with novel properties have been intensively studied both theoretically and experimentally. Within those developments, the interaction of atomic spins with electromagnetic waves (photons) and elastic dynamics (phonons) are of fundamental importance. This thesis is devoted to investigating the interplay of magnetism with electrodynamics and lattice elasticity in several hybrid systems.
