Abstract
We describe a technique which enables angle-resolved mapping of the in-plane Fermi velocity (vF) for a quasi-two-dimensional (Q2D) conductor. The method is based on a magnetic resonance effect in the ac conductivity for in-plane magnetic fields, which has recently been successfully applied to a Q2D organic conductor. In this article, we consider the possibility of using this method to probe the normal quasiparticles in nodal superconductors. We briefly explain the principle behind the conductivity resonance, and then present numerical simulations for the normal and superconducting states of a d-wave superconductor.
