Abstract
Energy levels and saturation of molecular nanomagnet Fe8 crystals were investigated using a 95 and 141 GHz electron paramagnetic resonance (EPR) technique based on a standard superconducting quantum intererence device (SQUID) magnetometer. The technique provides quantitative determination of the dc magnetic moment as a function of microwave power, magnetic field, and temperature.
