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…
