Probing Environmental Spin Polarization with Superconducting Flux Qubits
T. Lanting, M. H. Amin, C. Baron +6
We present measurements of the dynamics of a polarized magnetic environment coupled to the flux degree of freedom of rf-SQUID flux qubits. The qubits are used as both sources of po…

Variable-Range Hopping of Spin Polarons: Magnetoresistance in a Modified Mott Regime
M. Foygel, R. D. Morris, A. G. Petukhov
We analize electrical conductivity controlled by hopping of bound spin polarons in disordered solids with wide distributions of electron energies and polaron shifts (barriers). By…
