Tuning the properties of magnetic materials by voltage-driven ion migration (magneto-ionics) gives potential for energy-efficient, non-volatile magnetic memory and neuromorphic computing. Here, we report large changes in the magnetic moment at saturation (mS) and coercivity (HC), of 34% and 78%, respectively, in an array of CoFe2O4 (CFO) epitaxial nanopillar electrodes (∼50 nm diameter, ∼70 nm pitch, and 90 nm in height) with an applied voltage of −10 V in a liquid electrolyte cell.

Strain-gradient effects in nanoscale-engineered magnetoelectric materials / Nicolenco, Aliona (Universitat Autònoma de Barcelona. Departament de Física) ; de h-Óra, Muireann (University of Cambridge. Department of Materials Science and Metallurgy) ; Driscoll, Judith (University of Cambridge. Department of Materials Science and Metallurgy) ; Sort Viñas, Jordi (Universitat Autònoma de Barcelona. Departament de Física)
Understanding strain gradient phenomena is of paramount importance in diverse areas of condensed matter physics. This effect is responsible for flexoelectricity in dielectric materials, and it plays a crucial role in the mechanical behavior of nanoscale-sized specimens. [...]
