Abstract
We present a numerical simulation of angle dependent magnetoresistances osc illations(AMROs) in alpha-(BEDT-TTF)(2)KHg(SCN)(4). The nesting vector of t he density wave and the magnetic breakdowngap in the low-temperature, low-m agnetic-field state (LTLF) are constrained by simulations of quasi-one-dime nsional (Q1D) AMRO. Quasi-two-dimensional (Q2D) AMRO simulations for the hi gh-temperature, high-magnetic-field state (HTHF) allow the precise derivati on of an ellipticity of the Q2D Fermi surface. Simulations of the field dep endent AMRO demonstrate the gradual evolution of the FS from LTLF to HTHF s tates toward the kink transition at 23 T.
