Low-temperature transport in highly disordered films of superconducting magnesium diboride

Many features make magnesium diboride an interesting model system for understanding the behavior of two dimensional BCS superconductors, including its sensitivity to disorder and low spin-orbit coupling. We study the transport behavior of highly disordered magnesium diboride films, and will review preliminary low-temperature magnetoresistance measurements in the regime of high magnetic fields. We connect these results to recent work on multilayered films prepared using a similar process and also to similar work on other model systems, and review prospects for future study.
