WebWe report a new physical phenomenon of active and enhanced control of the spin Hall conductivity (SHC) in a family of metal-ferroelectric multilayers. Rather than the direction of the built-in electric field, such ferroelectric regulation of SHC originates from the drastic change of the interfacial electronic state along with its intrinsic Berry phase near the … WebEnter the email address you signed up with and we'll email you a reset link.
WebNov 25, 2024 · The intrinsic spin Hall effect plays an important role in spintronics applications, such as spin-orbit torque-based memory.
