Popis: Mechanically detected spin resonances The interaction of spins in a sample with a magnetic field can generate forces that can be sensed with cantilever probes. Losby et al. measured the resonance signals at room temperature with a micromechanical torque magnetometer. The difference between two applied radio-frequency signals corresponded to the mechanical frequency of the resonator. This approach revealed the vortex core dynamics of the ferri-toferro–magnetic transition in a micrometer-sized yttrium-iron-garnet single-crystal disk. Science , this issue p. 798
