Abstract

A light-weight portable electron spin resonance (ESR) spectrometer with the permanent magnet of Nd-B-Fe (Neomax) and field sweep coils was used as a demonstration tool of ESR microscopy for student’s experiments. Educational experiments on one-and two-dimensional ESR imaging are made by inserting field gradient coils or field scanning wire arrays into the cavity using test samples of DPPH. A preliminary work on double frequency modulation is described for two-dimensional imaging using microwire arrays.
