Information about funding sources that supported the collection of the data: This work was primarily supported by the National Science Foundation through DMR-2103711. Additional support (for B.K.) from Seagate Technology Inc. and the Advanced Storage Research Committee is acknowledged. Parts of this work were conducted in the Minnesota Nano Center, which is supported by NSF through the National Nanotechnology Coordinated Infrastructure under ECCS2025124, and in the UMN Characterization Facility, which is partially supported by NSF through the MRSEC program under DMR-2011401. DFT calculations (PD and TB) were supported by the Department of Energy through the UMN Center for Quantum Materials under grant number DE-SC0016371. We acknowledge P. Crowell and L. O’Brien for useful comments and discussions. 7. Overview of the data (abstract): Data prove the existence of the phase via x-ray diffraction, energy-dispersive x-ray spectroscopy, and electronic transport. The material is then evaluated with regard to spin transport through the use of non-local spin valves (NLSVs). The provided data can be used to determine the Elliot-Yafet parameters for defects and phonons that describe spin relaxation in this metal. -------------------------- SHARING/ACCESS INFORMATION -------------------------- 1.

Description of methods used for collection/generation of data: Band structure calculations were performed by Dutta and Birol. The experimental data were collected in the Leighton Lab at UMN and in the Characterization Facility at UMN. Equipment specifications are available in the published article and on the respective websites for the two labs. (https://leighton.cems.umn.edu/facilities and https://cse.umn.edu/charfac). 2. Methods for processing the data: The data presented are raw data for the most part and were generated as listed. Any data processing is thoroughly described in the published article and elsewhere and amounts to averaging of collected data and determination of the standard deviations in some cases. 3. Instrument- or software-specific information needed to interpret the data: None, all of the data are in plain text for ease of access. 4. Standards and calibration information, if appropriate: 5. Environmental/experimental conditions: Room temperature unless otherwise noted or where Temperature is the independent variable. 6. Describe any quality-assurance procedures performed on the data: 7. People involved with sample collection, processing, analysis and/or submission: The authors. General notes: NLSV = Non-Local Spin Valve DeltaRnl refers to the change in non-local resistance during NLSV measurements. RRR = residual resistivity ratio, defined as the 295 K resistivity divided by the 5 K resistivity. 2theta = scattering angle for diffraction measurements T = temperature XRD = x-ray diffraction ----------------------------------------- DATA-SPECIFIC INFORMATION FOR: DeltaRnl v separation for Al2Cu NLSVs.csv ----------------------------------------- 1.
