Carrier Density and Thickness Dependent Proximity Effect in Doped Topological Insulator -- Metallic Ferromagnet Bilayers

Yaron Jarach, Gad Koren, Netanel H. Lindner +1

We use magneto-conductivity to study the magnetic proximity effect on surface states of doped topological insulators. Our bilayers consist of a layer of Fe${}_7$Se${}_8$, which is a me…
