Fig. 2: Magnetic field dependence of the THz emission.
a THz emission amplitude measured as a function of in-plane magnetic field at selected temperatures. The dashed lines indicate the B-linear components of the signals. b Amplitude of both components sy(B−sat) and sy(B−linear) and their sum at +860 mT over the investigated temperature range. c Temperature dependence of \({S}_{y}^{*}\) for different magnetic fields up to +860 mT. The experiment was performed in the top-pumping geometry. Data sets without the correction for THz outcoupling and the information on the absorbed pump fluences are included in the SI. d Temperature dependence of Msat, coercive field Bc and exchange bias field Bex of the residual FM regions in FeRh-Pt.
