    Figures & Tables(5)
    The SdH oscillation of longitudinal resistivity (red line) and the Hall resistivity (black line) as a function of perpendicular magnetic field at 1.32 K
    Conductance correction and fitting results of WAL effect using ILP model in perpendicular magnetic field at different temperatures. The dotted lines are experimental data and the solid lines are the fitting results of ILP model. The inset gives the temperature dependence of the parameters Ωτ and τ/τϕ with red solid line is the fitting curve of τ/τϕ(T)~T
    Magnetoconductance and fitting results of WAL effect using modified ILP model in various in-plane magnetic fields at 1.32 K. The in-plane magnetic field intensity is given besides corresponding curve. The dotted lines are experimental results while the solids are fitting curve of the ILP model.
    The experimental and fitting results of the dependence of 1/(τ/τϕ(B//)) ratio on parallel magnetic field extracted by fitting the ILP model at various temperatures. The points are experimental data while the solid lines are fitting curves of Eq. 1. The inset gives the temperature dependence of the zero-field values of mr*g3*. The circles are obtained with Eq.2 and the square is inferred from fitting result of Eq.4
    The τ/τϕ(T) ratio as a function of temperature extracted by the ILP model. The dots are experimental data and the solid lines are fitting results of Eq. 3. The inset gives the dependence of τ/τϕ(B//) on B// when T= 0 K. The points are value of τ/τϕ(B//) obtained by Eq. 3 while the solid line is the fitting curve of Eq.4
