Zero-field pulsed spin echo spectrometer for the study of ferromagnetic materials

Abstract
Complete description of a pulsed nuclear-magnetic-resonance spectrometer operating in the frequency range 100–600 MHz is presented. The spectrometer is suitable for investigating hyperfine fields in ferromagnetic materials and has some novel features. High sensitivity, simplicity of operation, and ease of tuning over the entire frequency interval are some significant characteristics of the spectrometer.
