This dataset contains the information on our recent body of work on wireless magneto-ionics by bipolar electrochemistry approach and all the relevant data files. So far, magneto-ionics has been achieved through direct electrical connections to the actuated material. Here we evidence that an alternative way to reach such control exists in a wireless manner. Induced polarization in the conducting material immersed in the electrolyte, without direct wire contact, promotes wireless bipolar electrochemistry, an alternative pathway to achieve voltage-driven control of magnetism based on the same electrochemical processes involved in direct-contact magneto-ionics. A significant tunability of magnetization is accomplished for cobalt nitride thin films, including transitions between paramagnetic and ferromagnetic states. Such effects can be either volatile or non-volatile depending on the electrochemical cell configuration. These results represent a fundamental breakthrough that may inspire future device designs for applications in bioelectronics, catalysis, neuromorphic computing, or wireless communications.

1. Description of methods used for collection-generation of data: Various experimental tools were employed in this line of work, such as magnetron sputter for the materials growth, magnetometry for magneto-electric study, X-ray absorption and transmission electron microscopy for structural and microstructural inspections.

2. Methods for processing the data: The data files can be processed using Origin software, PowerPoint, and DigitalMicrograph.

3. Instrument- or software- specific information needed to interpret the data: For the magnetometry data, any antiferromagnetic signals were subtracted using the VSM software in our lab. The format of this dataset was converted into an open format that can be processed using Origin software.

4. Instruments, calibration and standards information: The VSM magnetometer was calibrated using a standard nickel pallet 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.

5. Environmental or experimental conditions: The measurements were conducted at ambient conditions.

6. 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 imminent publ
