Negative magnetoresistance in strained $\alpha$-Sn and $\alpha$-SnGe films in an in-plane magnetic field

Sunny Phan, Andrei Kogan, Jesse Thompson +3

To test the hypothesis that the chiral anomaly is responsible for negative magnetoresitance (MR) in \atn{}, we have studied magnetotransport in strained, epitaxial films of pure \a…
