This dataset, written in formal english, relates to the experimental data and methods used to carried out a published work, i.e. "Composition-dependent voltage-driven OFF-ON switching of ferromagnetism in Co-Ni oxide microdisks", at the ACS Applied Materials & Interfaces journal. The data collection renges from 2024-04-20 to 2024-12-02, and counts with numerous funding agencies, such as the European Research Council (Project number 2021-ERC-Advanced ‘REMINDS’ Nº 101054687), the Horizon Europe – NICKEFFECT (Project number 101058076), the Spanish Government (Project numbers PID2020-116844RB-C21 and PID2020 116844RB-C22) and the Generalitat de Catalunya (Project number 2021-SGR-00651).
Appart from the support received from the different institutions, we also acknowledge the equipment and service provided by the Surface Analysis Unit of the CCiTUB in the work for the XPS analysis carried out. The HRTEM characterization was performed at ALBA Synchrotron with the collaboration of ALBA staff.
The data were collected in Barcelona, Spain.
- Description of methods used for collection-generation of data:
Various experimental tools were employed in this line of work, such as electrodeposition for the materials growth, magnetometry for magneto-electric study, electron microscopy for high-resolution imaging, X-ray diffraction for phase identification or X-ray photoelectron spectroscopy for the elements chemical state identification.
- Methods for processing the data:
The data files can be processed using Origin software, PowerPoint, Gatan Digital Micrograph software, X’Pert HighScore and CasaXPS software.
- Instrument- or software- specific information needed to interpret the data:
For the magnetometry data, any paramagnetic signal was subtracted using the VSM software in our lab. Gatan Digital Micrograph software was used to analyze atomic-scale images of the investigated material. X’Pert HighScore helped searching and matching the experimental diffraction peaks. CasaXPS software was used for XPS peak deconvolution and a Shirley background was used for all elements. The format of this dataset was converted into an open format that can be processed using Origin software.
- Instruments, calibration and standards information:
The VSM magnetometer was calibrated using a standard nickel sample provided by the company (Micro Sense, LOT, Quantum Design). Magnetization data is shown in the paper as magnetic moment divided by the effective volume of the films. The XPS peak positions were normalized with respect to the Carbon peak (~284.8 eV).
- Environmental or experimental conditions:
The measurements were conducted in ambient conditions.
- Quality-assurance procedures performed on the data:
The results were carefully analyzed and interpreted. Peer review process of the corresponding scientific article by experts in this field has been done, and its publication in ACS Applied Materials & Interfaces was made satisfactory on December 27th of 2024.
