Ferroelectric-polarization modulation of charge-to-spin conversion in Pb(Mg1/3Nb2/3)O3–Pb0.7Ti0.3O3/La0.67Sr0.33MnO3 system
Source abstract
Abstract
Modulation of charge-to-spin conversion through active control is supposed to manipulate efficiency in a wide range for future spintronic devices. Despite its great significance, passive control still dominates the manipulation while the active control of charge-to-spin conversion is still challenging. Here we experimentally observe spin pumping-type charge-to-spin conversion besides Rashba-type one in La 0.67Sr 0.33MnO 3 thin films deposited on ferroelectric Pb(Mg 1/3Nb 2/3)O 3–Pb 0.7Ti 0.3O 3 (PMN-PT) substrate. We exhibit that both two types of charge-to-spin conversion efficiency give rise to a variety of sign under positive and negative remnant polarized states of PMN-PT, which can be ascribed to the effect of ferroelectric polarization. The possibility of modulating charge-spin conversion opens a route for designing low-energy spintronics.
