Abstract
Methods and apparatus for detecting (and, if desired, imaging) the effects of magnetic resonance in a spin-containing material by measuring the magnetic force acting on a mechanical cantilever having a low damping coefficient due to modulation of the magnetic moment of the material in the polarizing field direction at a frequency substantially lower than the spin resonance frequency. Modulation of the magnetic moment in the direction of the polarizing magnetic field may be achieved by modulating (i) the magnitude of the magnetic field in the polarizing direction or (ii) the frequency or amplitude of a high-frequency magnetic field.
