Resonant microwave power absorption and relaxation of the energy levels of the molecular nanomagnet Fe 8 using superconducting quantum interference device-based magnetometry

Energy levels and saturation of molecular nanomagnet Fe 8 crystals were investigated using a 95 and 141 GHz electron paramagnetic resonance (EPR) technique based on a standard superconducting quantum interference device (SQUID) magnetometer. The technique provides quantitative determination of the d...

Zusammenfassung:Energy levels and saturation of molecular nanomagnet Fe 8 crystals were investigated using a 95 and 141 GHz electron paramagnetic resonance (EPR) technique based on a standard superconducting quantum interference device (SQUID) magnetometer. The technique provides quantitative determination of the dc magnetic moment as a function of microwave power, magnetic field, and temperature.
