Longitudinal interlayer magnetoresistance in quasi-2D metals

Abstract

The longitudinal interlayer magnetoresistance $R_{zz}(B_z)$ is calculated in strongly anisotropic layered metals, when the interlayer band width $4t_z$ is less than the Landau level separation $\hslash {\omega }_c$. The impurity scattering has much stronger effect in this regime than in 3D metals and leads to a linear longitudinal interlayer magnetoresistance $R_{zz}\propto B_z$ in the interval $\hslash {\omega }_c>4t_z>>\sqrt{{\Gamma }_0\hslash {\omega }_c}$ changing to a square-root dependence $R_{zz}\propto B_z^{1/2}$ at higher field or smaller $t_z$. The crossover field allows to estimate the interlayer transfer integral as $t_z\sim \sqrt{{\Gamma }_0\hslash {\omega }_c}$. Longitudinal interlayer magnetoresistance, being robust to the increase of temperature or long-range disorder, is easy for measurements and provides a useful tool to investigate the electronic structure of quasi-two-dimensional compounds.
