Field-flattened optical-access split-coil cryostat magnet for THz EPR Ellipsometry
Abstract
Field-flattened optical-access split-coil cryostat magnet The PI proposes acquisition of such instrument to establish the first-of-its-kind research facility; Terahertz (THz) electron paramagnetic resonance (EPR) ellipsometry (THz-EPR ellipsometry). The new THz-EPR ellipsometry facility at the University of Nebraska-Lincoln will enable a new way to perform EPR with unparalleled feasibility, strongly improved sensitivity, and with access to hitherto unavailable information of electron spins in simple and complex environments. Here, the full tensor of the complex-valued magnetic susceptibility of resonance transitions related to unpaired electron spins is measured, both as a function of freely tunable continuous-wave (cw) THz frequency and freely tunable magnetic field amplitude, with very high spectral resolution (less than1 ppm) and very high magnetic resolution (less than100 ppm), from any optically addressable spin resonance, in the frequency region from 100 GHz to 1 THz, and for magnetic fields between -8 T and +8 T.
