Our research objective was to develop a theoretical model describing the precession of flux-pinned magnetized materials in addition to the subsequent generation of spin currents within the superconductor. Our mathematical analysis incorporated thermal, electromagnetic, and quantum phenomena, including the Bloch-3/2 relation, Barnett effect, and spin-enhanced electron-phonon coupling. We further developed a novel consideration of the London moment in the vortex state as well as a framework for spin currents in superconductors dependent on the applied magnetic field and rotation of the superconductor. Conclusive data was first provided by MATLAB simulations, allowing us to identify the steady-state solutions to our mathematical model as well as perform critical field calculations for various superconductors. We further introduced experimental test benches for a yttrium barium copper oxide (YBCO) superconductor, particularly focusing on verifying our model for the precession of ferromagnets as well as the detection and measurement of spin currents. A statistical analysis revealed p-values below .0005 displaying the statistical significance of our results. Ultimately, we look to apply these models to deep space exploration, improving the integration of superconductors into spacecraft. The steady-state rotation of a ferromagnet levitated above a superconductor (or vice versa) can be used to enhance existing London moment gyroscopes and superconducting quantum interference devices (SQUIDs) for application to inertial navigation systems such as control moment gyroscopes. Additional applications include electricity generation for application to magnetoplasmadynamic thrusters and utilizing Abrikosov vortex dynamics and spin currents in superconductors for spintronic data storage and logical computations.
