Second harmonic Hall (SHH) measurements. (a) The crystal structure of Mn3Ni0.35Cu0.65N (MNCN) with the spins in the Γ4G configuration. (b) Schematic representation of SHH measurements. Measured first harmonic voltages (V 1ω) by rotating the magnetic field (H ext ) in the plane to determine V P (c) and sweeping the magnetic field out of the plane to determine V A and H ⊥ (d). (e) Measured second harmonic Hall voltage (V 2ω) signal for two different values of H ext . (f) Fitting of the experimental data (red squares) with the contribution from DLT (pink curve) and FLT (blue curve). (g, h) Extracted values of C A and C P as a function of H ext .
