Anisotropy of the ferromagnetic transition. a R(Η) curves of Sample A at T = 3 K and θ = 90°, 135° and 180°. HFM is the magnetic field above which the system is in the ferromagnetic state. HFM* indicates a possible phase transition. HCR is the magnetic field above which the magnetoresistance at H \(\parallel\) <011> is smaller than that at H \(\parallel\) [010] and H \(\parallel\) [\(00\bar 1\)]. b Angle dependence of HFM (solid symbols) and HFM* (open symbols). The dashed lines represent 1/cosφ with φ = θ − nπ/2 with n = 1, 2, and 3 for 90° ≤ θ ≤ 135° and 135° ≤ θ ≤ 225°, and 225° ≤ θ ≤ 270°, respectively (see text for more discussion). c Phase diagrams HFM vs T for the ferromagnetic states at H \(\parallel\) [010] and H \(\parallel\) [011] and for HCR, above which orbital-flops appear as clear magnetoresistance minima in the R(θ) curves. Results indicate that orbital-flop effect is most pronounced in the ferromagnetic phase. d, Magnetoresistances at μ0H = 7T and temperatures from 3 K to 25 K. Orbital-flop induced minima can be seen at θ = 45°, 135°, 225° and 315°, i.e., H \(\parallel\) < 011 > at T < 10 K
