Magnetoconductance ΔG versus magnetic field B for CBS films for PMN-PT substrates in \(P_r^ +\) and \(P_r^ -\) states. a ΔG for CBS films with different thicknesses measured at a fixed temperature (T = 2 K). b ΔG for the 6 nm CBS film, as measured at different temperatures of T = 2, 5, 10, 20, 30, and 50 K, respectively. The blue and red solid curves represent the fitting results obtained using Eq. (3)
