THz E-field emitted by CoFeB/10 ML PtSe2(red), CoFeB/10 ML WSe2(blue), CoFeB/10 ML VSe2(green), CoFeB/Gr reference sample (grey), and bare Gr/SiC substrate (pink). The arrows indicate the position of the first THz E-field peak: positive for PtSe2and negative for WSe2, VSe2, and reference sample. All the measurements were carried out in reflection mode with a 15 fs laser pulse and 1 mm ZnTe detector and with a fixed 20 mT (B+) applied magnetic field.
