Terahertz Spintronic Emitter Measurements for Polarization Control

Raw data from terahertz time-domain spectroscopy and vibrating sample magnetometry measurements of FeCo/TbCo2/FeCo trilayer spintronic emitters. The dataset includes comparisons of emitter performance on different substrates, magnetic hysteresis data, and demonstrations of magnetically controlled polarization rotation. It was created by Pierre Koleják of the Centre National de la Recherche Scientifique.

Use Cases

• Comparing spintronic emitter performance based on substrate material and measurement configuration data.
• Analyzing magnetic hysteresis behavior based on VSM and THz-TDS measurements.
• Studying magnetically controlled polarization rotation of terahertz waveforms.
• Benchmarking terahertz spectroscopy applications, such as quartz analysis, using spintronic emitter data.

Strengths

• Includes data from two established measurement techniques: terahertz time-domain spectroscopy and vibrating sample magnetometry.
• Contains comparative data for emitter performance in both reflection and transmission configurations.
• Provides raw data for orthogonal magnetization vectors across different material layers and axes.

Limitations

• Column-level documentation is absent; field semantics must be inferred from file and column names after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
