A novel spin resonance microscope is disclosed, the microscope design comprising an integrated evanescent wave probe and scanning tunneling microscope tip. The probe and tip may be either the same structure, or they may be separate structures. The integrated design allows for coherent excitation of precessing electron spin states in the sample such that spin resonance may be detected because the tunneling current is modulated by the spin resonance. Spin resonance may be affected by either adjacent nuclei, or by adjacent electrons. The present apparatus requires significantly reduced power inputs, such that the dead time of the system is short, and relaxation phenomena may be evaluated without swamping the instrument's electronics.
