Variation of cantilever frequency with field where the ferrite moment at the tip is initially aligned with the field.
(a) Schematic of the cantilever and fiber arrangement; (b) the cantilever and sample relative to the flange of the corrugated feedhorn. Not to scale.
Simplified diagram of the quasioptical ESR system with focusing elements omitted.
Overall schematic of high field FDMR experiment. The magnet is omitted for clarity.
Amplitude and phase modulated force detected ESR spectra of fluoranthene with the cantilever in air at room temperature. The vertical dashed line shows the position of the line measured by conventional high field ESR.
Frequency modulated force detected ESR spectrum of fluoranthene taken in a vacuum of with a cantilever of 3100.
Model AM FDESR spectra for a thick cylindrical sample with diameter. The dashed line is for a probe center to sample surface separation of , and the solid line is for a separation of . The millimeter-wave field magnitude used in the model was , corresponding to a power of .
