Energy scans of \({\sigma }_{x}^{\mathrm{SF}\,}\) (red circle), \({\sigma }_{y}^{\mathrm{SF}\,}\) (green diamond), and \({\sigma }_{z}^{\mathrm{SF}\,}\) (blue square) under a, b P = 0 and T = 138 K34 and c, d  ~20 MPa and T = 145 K at the two AF wave vectors Q1 = (1, 0, 1) and Q2 = (1, 0, 3). e, f Comparison of P = 0 and P ≈ 20 MPa \(({\sigma }_{z}^{\mathrm{SF}\,}-{\sigma }_{y}^{\mathrm{SF}\,})\) at (1, 0, 1) and (1, 0, 3). g, h Energy dependence of Ma, Mb, and Mc extracted from the raw data in (a–d). The solid lines are guides to the eyes and the error bars represent 1 standard deviation.
