Patent ID: 7268546

Claim:
A method for spatially resolved spin resonance spectroscopy in a material sample, the method comprising: exciting a sample with a first magnetic field, the first magnetic field having a field component along a first direction at a first location on the sample; applying a second magnetic field to the sample, the second magnetic field having a field component along a second direction, the second direction being substantially perpendicular to the first direction, wherein the first magnetic field and the second magnetic field interact with at least one spin for at least one atomic constituent at the first location to produce a spin resonance; and sensing the spin resonance of the at least one spin using an evanescent wave probe located adjacent to the first location, wherein the spin resonance is selected from a group consisting of electron spin resonance and ferromagnetic resonance, wherein sensing the spin resonance includes making a time-resolved measurement of at least one property of the spin resonance.
