Abstract

See full text

A magnetic resonance force microscope (MRFM) generator for producing an RF magnetic field uniformly over the whole of a sample. A cantilever with magnetic probe tip is self-excited. Under this condition, spins in the sample are controlled to produce a magnetic resonance force. A frequency demodulator measures the resonant frequency of the cantilever from the output detection signal from a cantilever displacement-measuring instrument based on the magnetic resonance force.
