Contribution
It presents a novel multifrequency nanomechanical approach to measure AC susceptibility and its harmonics at the single-element level, distinguishing nonlinearities from hysteresis.
Findings
Reversible nonlinearities identified in YIG magnetization
Separation of AC susceptibility signals from hysteretic jumps
Enhanced understanding of mesoscopic magnetic responses
Abstract
A novel method for simultaneous detection of both DC and time-dependent magnetic signatures in individual mesoscopic structures has emerged from early studies in spin mechanics. Multifrequency nanomechanical detection of AC susceptibility and its harmonics highlights reversible nonlinearities in the magnetization response of a single yttrium iron garnet (YIG) element, separating them from hysteretic jumps in the DC magnetization.
