Extended Data Fig. 9: Anomalous Nernst effect measured under different temperature gradients in the [Ta/Co20Fe60B20/MgO]15 multilayer.
From: Thermal generation, manipulation and thermoelectric detection of skyrmions
a, The evolution of anomalous Nernst voltages (VANE) measured with different currents supplied into the heater (IHeater). b, Following the increase of IHeater, a parabolic increase of saturated VANE(μ0H⊥ = 100mT) can be found. c, The evolution of VANE(μ0H⊥ = 100 mT) as a function of ∇T(x). d, The time evolution of VANE measured at a fixed IHeater = 3 mA and μ0H⊥ = 25 mT, after switching off skyrmion generation currents (from 3.5 mA to 6 mA in 0.5 mA steps). Upon removing the increased DC currents used for generating skyrmions, discretized steps are gradually resolved. e, The corresponding IHeater as a function of time used for the ANE measurement in d.
