Longitudinal Spin-Hall magnetoresistance (SMR) in the β-plane of Pt Hall bars deposited along the y-axis. a Field dependence of the longitudinal SMR signal for magnetic fields applied parallel (β = −30o) and perpendicular (β = 60o) to easy axis and for two intermediate orientations in the xz plane (β = 0o and 90o). b Dependence of the longitudinal SMR (color code) as a function of the amplitude and direction of the magnetic field in the xz plane calculated from the model (1)–(3) with \({{H}}_{{\rm{an}}}^{{\rm{eff}}} =\) 23.8 mT, \({{H}}_ \bot =\) 1.54 μT, and \({{H}}_{{\rm{DMI}}} =\) 2.72 T. Solid line (theory) and dots (experiment) show the angular dependence of the critical field. Vertical arrows correspond to the extracted critical fields. (a). The angle β is calculated from x-axis, the current is applied along y, as shown in Fig. 1a. In calculations we account for a shift between crystallographic and experimental axes, \({{\chi }}_{{H}} = ({{\beta }} + 33)^\circ\). The sample temperature is T = 200 K. Error bars (if not visible, smaller than the symbol size) account for (a) the standard error, (b) fit parameters errors and saturation field uncertainty
