Electron Spin Resonance Technique

AbstractThe electron spin resonance technique has been applied to study the magnetization dynamics in broad temperature range in both concentrated magnetic fluid and diamagnetically diluted systems containing superparamagnetic maghemite nanoparticles. The ESR spectrum demonstrates an interesting double feature shape with a narrow peak near g=2, as well as “forbidden” resonances in low fields, and reveals strong dependence on temperature and nanoparticle concentration. The longitudinal spin-relaxation time was estimated. To describe the overall spectrum shape, a “quantization” model is used which involves summation of the resonance transitions corresponding to various orientations of the particle magnetic moment.
