Fully reversible magnetoelectric voltage controlled THz polarization rotation in magnetostrictive spintronic emitters on PMN-PT

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).本数据集包含用于演示自旋电子发射器太赫兹偏振磁电调控的实验数据。其中，名为“垂直电场幅值（Vertical E-field amplitude）”与“水平电场幅值（Horizontal E-field amplitude）”的文件，记录了不同外加电压下测得的正交偏振太赫兹波旋转特性。“电场峰值旋转（E-field peak rotation）”文件展示了太赫兹信号峰值处的偏振调控效果，其数据按不同偏置磁场（单位：安培/米，A/m）分组。产生磁弹性各向异性的应变测量数据可在“pmn-pt-strain”文件中获取。“磁滞 - STEmulti-PMN-PT”文件包含易磁化轴（Easy Axis, EA）与难磁化轴（Hard Axis, HA）的磁滞回线。
