We propose a detection method for magnetic resonance experiments based on the use of a Hall effect device. To demonstrate its feasibility, we have measured the quasistatic and radio-frequency magnetic fields generated by the unpaired electrons contained in a (50 μm)3 grain of diphenylpicrylhydrazil, excited into magnetic resonance in a 10 mT static magnetic field. The proposed technique has the same versatility of the conventional inductive method but, potentially, allows one to perform magnetic resonance spectroscopy and imaging studies with submicron spatial resolution. © 2001 American Institute of Physics.
