The Einstein - de Haas effect at radio frequencies in and near magnetic equilibrium
K. Mori, M. G. Dunsmore, J. E. Losby +3
The Einstein-de Haas (EdH) effect and its reciprocal the Barnett effect are fundamental to magnetism and uniquely yield measures of the ratio of magnetic moment to total angular mo…
Two-axis cavity optomechanical torque characterization of magnetic microstructures
Ghazal Hajisalem, Joseph E. Losby, Gustavo de Oliveira Luiz +3
Significant new functionality is reported for torsion mechanical tools aimed at full magnetic characterizations of both spin statics and dynamics in micro- and nanostructures. Spec…
Recent Advances in Mechanical Torque Studies of Small-scale Magnetism
Joseph E. Losby, Vincent T. K. Sauer, Mark R. Freeman
There is a storied scientific history in the role of mechanical instruments for the measurement of fundamental physical interactions. Among these include the detection of magnetic…
Broadband optomechanical transduction of nanomagnetic spin modes
P. H. Kim, F. Fani Sani, M. R. Freeman +1
The stable vortex state that occurs in micron-scale magnetic disks is one of the most interesting and potentially useful phenomenon in nanomagnetism. A variety of tools have been a…
Magnetic Actuation and Feedback Cooling of a Cavity Optomechanical Torque Sensor
P. H. Kim, B. D. Hauer, T. J. Clark +3
We demonstrate the integration of a mesoscopic ferromagnetic needle with a cavity optomechanical torsional resonator, and its use for quantitative determination of the needle's mag…
Nanocavity optomechanical torque magnetometry and radiofrequency susceptometry
Marcelo Wu, Nathanael L. -Y. Wu, Tayyaba Firdous +4
Nanophotonic optomechanical devices allow observation of nanoscale vibrations with sensitivity that has dramatically advanced metrology of nanomechanical structures [1-9] and has t…
