abstract = "We report on a large linear magnetoresistance effect observed in
doped p-PbTe films. While undoped p-PbTe reveals a sublinear
magnetoresistance, p-PbTe films doped with BaF2 exhibit a
transition to a nearly perfect linear magnetoresistance behaviour
that is persistent up to 30 T. The linear magnetoresistance slope
R/B is to a good approximation, independent of temperature. This
is in agreement with the theory of Quantum Linear
Magnetoresistance. We also performed magnetoresistance simulations
using a classical model of linear magnetoresistance. We found that
this model fails to explain the experimental data. A systematic
study of the doping dependence reveals that the linear
magnetoresistance response has a maximum for small BaF2 doping
levels and diminishes rapidly for increasing doping levels.
Exploiting the huge impact of doping on the linear
magnetoresistance signal could lead to new classes of devices with
giant magnetoresistance behavior.",
