Abstract
The invention provides an electron spin resonance device in which a measuring sample is arranged in a cavity resonator in a polarization magnetic field for a receipt of a predetermined microwave power and a subsequent resonance signal detection from said sample. A microwave signal amplifier is arranged on a prestage of a microwave detection circuit for an addition of a part of an output from a microwave oscillator at an input terminal of said amplifier so as to accomplish a balanced cancellation of a microwave reflective power from said cavity resonator.
