Nanomagnetomechanical resonators

Motivated by functions that could be enabled with combined nanomechanical and nanomagnetic structures, we have embarked on a program of fabrication and characterization of nanomagnetomechanical systems. Fabrication strategies include conventional electron beam lithography with release from a sacrificial layer, and focused ion beam nanomachining of “2D” and “3D” precursor materials. Characterization approaches incorporate frequency-domain and time-domain techniques, with the latter extending out to GHz scales. Fundamentally and for applications, the dynamics of nanomagnetomechanical systems must be understood from a time domain perspective, requiring expansion of the range of studies and applications of nanomechanical systems beyond those emphasizing frequency domain operation.
