Novel Magnetoacoustic Resonance Technique for Exploring Hidden Quadrupoles in a Crystal Field Quartet
Mikito Koga, Masashige Matsumoto
Crystal field quartets with quadrupole degrees of freedom play a crucial role in hidden ordering systems, as exemplified by CeB. We present a novel magnetoacoustic resonance te…
Theory of Magnetoacoustic Resonance to Probe Multipole Effects Due to a Crystal Field Quartet
Mikito Koga, Masashige Matsumoto
We present a new method of acoustically driven resonance that probes octupole degrees of freedom as well as a quadrupole usually hidden by the magnetic properties of a crystal fiel…
Theory of Spin-Acoustic Resonance for Spin-3/2 Si Vacancy with Site Symmetry in Silicon Carbide
Mikito Koga, Masashige Matsumoto
Motivated by the recent acoustically driven spin resonance studies applied to silicon vacancy centers in silicon carbide, we theoretically investigate the spin--strain interaction…
Theory of Field-Angle-Resolved Magnetoacoustic Resonance in Spin-Triplet Systems for Application to Nitrogen-Vacancy Centers in Diamond
Mikito Koga, Masashige Matsumoto
Motivated by the recent studies of acoustically driven electron spin resonance applied to diamond nitrogen-vacancy (NV) centers, we investigate the interaction of an electronic spi…
Magnetoacoustic Resonance to Probe Quadrupole-Strain Coupling in a Diamond Nitrogen-Vacancy Center as a Spin-Triplet System
Mikito Koga, Masashige Matsumoto
A theory of magnetoacoustic resonance is proposed to measure quadrupole-strain couplings in a spin-triplet state with the point group symmetry, considering the spin-strain…
Theory of Photon-Assisted Magnetoacoustic Resonance as a New Probe of Quadrupole Dynamics
Mikito Koga, Masashige Matsumoto
Motivated by the recent progress of phonon-mediated control in quantum spin devices, we propose a possibility of hybrid measurement using electron paramagnetic resonance (EPR) and…
