As CMOS technologies face challenges in dimensional and voltage scaling, the demand for novel logic devices has never been greater, with spin-based devices offering scaling potential, at the cost of significantly high switching energies. Alternatively, magnetoelectric materials are predicted to enable low-power magnetization control, a solution with limited device-level results. Here, we demonstrate voltage-based magnetization switching and reading in nanodevices at room temperature, enabled by exchange coupling between multiferroic BiFeO and ferromagnetic CoFe, for writing, and spin-to-charge current conversion between CoFe and Pt, for reading.

- The development of spintronic devices, like MESO logic devices, is hindered by low signal strength used for magnetization readout, highlighting the need for materials with better spin-to-charge conversion efficiency.
- We showcase all-electrical spin-to-charge conversion in BiSe nanodevices, revealing that the efficiency can be significantly overestimated based on the metal contact used.
- The study emphasizes that intermixing at material junctions can change properties like resistivity and spin Hall angle, and discusses strategies to enhance spin-to-charge conversion signals in these structures for practical applications.
