Fully reversible magnetoelectric voltage controlled THz polarization rotation in magnetostrictive spintronic emitters on PMN-PT
<p>The files include experimental data to demonstrate magneto-electric control of terahertz polarization of spintronic emitters. The files called "Vertical E-field amplitude" and "Horizontal E-field amplitude" describe the terahertz wave rotation for orthogonal polarizations measured for different values of applied voltage. The files "E-field peak rotation" show the control of polarization at the peak of the terahertz signal and differs by magnetic field bias (A/m). The measurement of the strain creating the magnetoelestic anisotropy can be found in the file "pmn-pt-strain". Files "Hysteresis - STEmulti-PMN-PT" contain magneto-hysteresis loops for easy (EA) and hard axis (HA).</p>
