Abstract:
1. An integrated EWP-STM spin resonance microscope, the microscope comprising: a microwave/RF resonator cavity coupled to an input power source and an output signal circuit; an evanescent wave probe (EWP) connected to one end of the resonator cavity, the probe configured to coherently excite a precessing electron spin state in an adjacent sample, the precessing electron spin state having a spin resonance frequency; and a scanning tunneling microscope (STM) comprising a bias voltage circuit connected to the resonator cavity and to the sample such that the EWP functions also as the tip of the STM; wherein the tunneling current from the STM circuit is modulated by the spin resonance frequency, thereby enabling the detection of a spin resonance in the sample.
