“…The present compound shows that the peak width clearly decreases with increasing magnetic field, and that the magnetoresistance at approximately θ = 90 • is scaled by B cos θ Kennett and McKenzie have proposed a new model for the 90 • peak in the angulardependent magnetoresistance [18]. They have considered quantum correction to the semiclassical conductivity in the incoherent layered system, and found that the 90 • peak appears owing to the weak localization effect.…”

Interlayer Charge Disproportionation in the Layered Organic SuperconductorκH−(DMEDO−TSeF)2[Au

We report the molecular dipole effect on conduction electrons in the title superconductor. The angular-dependent magnetoresistance has a peak for fields nearly parallel to the conducting layer, and the peak width scales as the field component perpendicular to the layer, indicating incoherent interlayer transport. However, two closed Fermi surfaces are observed in quantum oscillation. Accordingly, crystallographically independent layers have different charge densities in a bulk single crystal. The electric dipole of tetrahydrofuran gives rise to interlayer charge disproportionation.

“…It should be emphasized that the model calculation above is too simplistic to be directly applied to the interlayer resistivity data mentioned in this section. (There are certain low-dimensional organic metals, with a multilayered structure and single-layer Fermi surfaces that are rotated with respect to each other, for which this model is more suitable [26][27][28] (see footnote 1).) The main point of this paper is that the semiclassical magnetotransport in a system composed of inequivalent, weakly coupled layers with discrete Fermi surface intersections is qualitatively distinctive.…”

“…Consequently, the model captures the essential physics and properties (i), (ii) and (iii) above are predicted for generic multilayer systems. (I discuss the connection between the model calculation and existing experimental data near the end of the paper, see also 1 [26][27][28].) The advantage of considering a particular simplified model of a bilayer metal is that analytic expressions that provide insight into the key properties are readily obtained.…”

The interlayer magnetotransport of a model layered metal is calculated semiclassically. Each layer contains parallel quasi-1D wires but the orientation of wires within each layer is perpendicular to the orientation of wires in adjacent layers. The model has a highly anisotropic amplitude for interlayer electron transfer and is used to illustrate simply the effects that this anisotropy has on the magnetotransport. Strong positive magnetoresistance is calculated for magnetic fields parallel to the current, with the size of magnetoresistance varying inversely with the interlayer hopping amplitude. For fields perpendicular to the current, the magnetoresistance depends qualitatively on the orientation of the field: it scales linearly with the field strength B when the field points toward intersections of 1D Fermi surfaces belonging to individual layers, and scales as √B when the field points between intersections. In a weak field, the resistance is maximum when the field is orientated parallel to the current and minimum when it is perpendicular to the current. Magnetoresistance oscillations are also studied. The implications for more general models of multilayer metals are discussed.

Studies of interlayer transport in layered metals have generally made use of zero temperature conductivity expressions to analyze angle-dependent magnetoresistance oscillations (AMRO). However, recent high temperature AMRO experiments have been performed in a regime where the inclusion of finite temperature effects may be required for a quantitative description of the resistivity. We calculate the interlayer conductivity in a layered metal with anisotropic Fermi surface properties allowing for finite temperature effects. We find that resistance maxima are modified by thermal effects much more strongly than resistance minima. We also use our expressions to calculate the interlayer resistivity appropriate to recent AMRO experiments in an overdoped cuprate which led to the conclusion that there is an anisotropic, linear in temperature contribution to the scattering rate and find that this conclusion is robust.
