Deterministic Electrical Control of Single Magnetic Bubbles in Nanostructured Cells
Abstract Localized particle‐like spin textures have been found to exhibit emergent electromagnetic properties, which hold promise for the development of intriguing spintronic devices. Among these textures, magnetic bubbles represent localized spin configurations that could serve as data bits. However, the precise methods for their electrical manipulation remain uncertain. Here, the deterministic electrical manipulations and detections of single magnetic bubbles in kagome‐latticed Fe 3 Sn 2 magnetic nanostructured cells are demonstrated. The current‐induced dynamics of magnetic bubbles are explored using nanosecond pulsed currents. It is shown that single pulsed currents with low and high densities can be applied for the creation and deletion of a single bubble, respectively. The mutual writing‐deleting operations on single bubbles are attributed to the thermal heating and non‐thermal spin‐transfer torque effects in combination with micromagnetic simulations. The in situ detection of a single bubble using the anisotropic magnetoresistance effect through a standard four‐probe method is also realized. The results can propel the development of bubble‐based spintronic devices.
