Electron Paramagnetic Resonance of Material Properties and Processes

Abstract

The purpose of this paper is to demonstrate, primarily for the non-specialist and within the context of new and recent achievements, the diagnostic value --~ of electron paramagnetic resonance (EPR) in the study of material properties and processes. I have selected three EPR studies which demonstrate tne elegance and uniqueness of EPR in atomic defect studies and exemplify unusual achievements through the use of new techniques for material measurement and preparation. A brief introduction into the origin, interaction, and detection of unpaired electrons is included.
