ABSTRACT:
A heterodyne pumping method and system are provided for producing gyromagnetic resonance in a sample. The system includes a unidirectional static magnetic field for polarizing the sample. A first oscillating magnetic field having a first frequency is applied to said sample in the direction of said static magnetic field. A second oscillating magnetic field having a second frequency is applied transverse to said static magnetic field. A magnetic resonance response exhibited by said sample is detected and filtered by a bandpass filter so as to eliminate any drive signal interference. First and second oscillating magnetic fields are selected having first and second frequencies that provide wideband frequency separation from the resonance frequency of the sample.
