摘要

In strongly anisotropic quasi-two-dimensional (2D) metals, where the interlayer band width is less than the Landau level separation, the role of impurity scattering is enhanced by a magnetic field perpendicular to the conducting layers. This leads to a longitudinal magnetoresistance (MR) in contrast to the prediction of classical theory based on the constant-r approximation. The MR has a square-root dependence R_(zz) (B_z) in a strong field, being linear in the intermediate region. The crossover field allows to estimate the interlayer transfer integral or electron mean-free time. Longitudinal interlayer MR, 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-2D compounds.
