Figure 3.

(a) Resistivity ρ versus field μ₀H shows significant antisymmetric component in needle A and B. The lower inset cartoon illustrates the geometric definition for angles of γ, ϕ, and θ. (b) Extracted antisymmetric components (ρ_antisym) in MR of needle A at four different θ angles. At μ₀H = 15 Tesla, the angular dependence of extracted symmetric (ρ_sym) and antisymmetric (ρ_antisym) components of needle A and B are shown in (c,d), respectively. The lower panel shows the corresponding SdH frequencies that can be identified from the FFT spectra. The major SdH frequencies F₁ (black circles) at about 61 Tesla and 27 Tesla for needle A and B, respectively, both show weak angular dependence. Secondary SdH frequencies F₂ appear at some angles shown as red diamonds.
