Refining the Two-Band Model for Highly Compensated Semimetals Using Thermoelectric Coefficients
Ian Leahy, Andrew Treglia, Gang Cao +2
In studying compensated semimetals, the two-band model has proven extremely useful in capturing electrical conductivity under magnetic field, as a function of density and mobility…

Non-saturating large magnetoresistance in semimetals
Ian A. Leahy, Yu-Ping Lin, Peter E. Siegfried +4
The rapidly expanding class of quantum materials known as {\emph{topological semimetals}} (TSM) display unique transport properties, including a striking dependence of resistivity…

Multiple magnetic states within the A-phase determined by field-orientation dependence of Mn0.9Fe0.1Si
Peter E. Siegfried, Alexander C. Bornstein, Andrew C. Treglia +2
We report three distinct regions within the A-phase in Fe-doped MnSi, based on the evolution of magnetoresistance and the Hall effect as a function of orientation of applied field.…
