Researchers demonstrate electrical control of magnetic dimer entanglement via ferroelectric switching

Yuefei Liu and colleagues at Uppsala University, in collaboration with AlbaNova University, Chinese Academy of Sciences, Swedish e-Science Research Centre (SeRC), and KTH Royal Institute of Technology, have identified quantum corrections to the Gilbert damping mechanism through ferroelectric control of a magnetic dimer.

Their ab initio calculations and quantum simulations reveal that switching the ferroelectric polarisation alters the magnetic exchange interaction, offering a means to manipulate and diagnose entanglement dynamics via measurable magnetisation traces.

This provides a minimal, non-volatile platform linking first-principles modelling to experimentally accessible observables, previously a major challenge in spintronics.
