360° polarization control of terahertz spintronic emitters using uniaxial FeCo/TbCo2/FeCo trilayers

<p>The attached files contain raw data&nbsp;&nbsp;of terahertz spintronic emitters (STE) measured with terahertz time-domain spectroscopy (THz-TDS) and vibrating sample magnetometry (VSM). The file name indicates what was measured and the individual column names in the file describe the measured quantities.</p> <p>STE_comparison_reflection.csv provides a comparison of the performance of the proposed spintronic emitter integrated on various substrates in a reflection configuration of THz-TDS. STE_comparison_transmission.csv compares the developed spintronic emitter with a reference sample in a transmission configuration. &nbsp;The data files starting with &#39;VSM_magnetization_&#39; contain VSM measurements of orthogonal magnetization vectors for FeCo, TbCo2, and the proposed trilayer for both easy (EA) and hard axes (HA). &nbsp;&nbsp;The magnetic hysteresis of the spintronic emitter is shown in the files VSM_hysteresis_STE.csv, TDS_hysteresis_mx_STE.csv, and TDS_hysteresis_my_STE.csv obtained using THz-TDS and VSM measurement techniques. The file TDS_polarization_rotation.csv demonstrates magnetically controlled polarization rotation of terahertz waveforms. The last file, TDS_quartz_analysis.csv, involves an application example of using a spintronic emitter for terahertz spectroscopy in quartz analysis.</p>
