Ionic Liquid Gating Control of Spin Wave Resonance in La_0.7Sr_0.3MnO₃ Thin Film

Abstract

heating-free propagation. [1-5] Compared with the traditional electronic computer platforms, spin wave based platforms have significant strengths in size and efficiency. [1,4-6] In recent decades, voltagedriven magnetoelectric (ME) coupling effect, not limited by the requirement of the device size or the conductivity of the control object, has been proved to be a shortcut and energy efficient method. [7-12] The fundamental voltage tunable phenomena, like control the interplay among the charge, lattice, orbital, and spin degrees of freedom, have also been investigated. [1,13-17] To manipulate the magnonics with the assistance of polarized voltage turns out to be considerably effective in further reducing the device size and power consumption of the future electronics/spintronics.

Hydrogen Control of Double Exchange Interaction in La0.67Sr0.33MnO3 for Ionic–Electric–Magnetic Coupled Applications

“…Annealing at extremely high temperatures (>500 °C) for several days was necessary to tailor both electrical and magnetic properties through cycling oxygen desorption and absorption, [ 15 ] which could lead to a problematic segregation of strontium particles on the film surface. [ 16 ] Although ionic liquid gating has been successfully used to control the physical properties at room temperature, [ 17–20 ] liquid phase gate materials are more difficult to use in technological applications.…”

Manipulations of Spin Waves by Photoelectrons in Ferromagnetic/Non‐Ferromagnetic Alloyed Film

“…Significant interfacial charge accumulation induces prolonged large electrochemical potential differences, resulting in chemical corrosion. [ 34 ] Herein, how to effectively control the spin wave in a low‐power behavior without chemical corrosion issues is urgent.…”
