Electrically induced ionic motion offers a new way to realize voltage-controlled magnetism, opening the door to a new generation of logic, sensor, and data storage technologies. Here, we demonstrate an effective approach to magneto-ionically and electrically tune the exchange bias in Gd/Ni1-xCoxO thin films (x = 0.50 and 0.67), where neither of the layers alone is ferromagnetic at room temperature. The Gd capping layer deposited onto antiferromagnetic Ni1-xCoxO initiates a solid-state redox… Expand


Magneto-ionic control of magnetism using a solid-state proton pump
This work shows reversible and non-destructive toggling of magnetic anisotropy at room temperature using a small gate voltage through H+ pumping in all-solid-state heterostructures, and provides a platform for voltage-controlled spin–orbitronics. Expand
Magneto-ionic control of interfacial magnetism.
It is shown that electrical switching of the interfacial oxidation state allows for voltage control of magnetic properties to an extent never before achieved through conventional magneto-electric coupling mechanisms, and suggests a path towards voltage-programmable materials based on solid-state switching of interface oxygen chemistry.

Interfacial-Redox-Induced Tuning of Superconductivity in YBa2Cu3O7-δ.
This work demonstrates an effective ionic control of superconductivity in oxides, an interface induced effect that goes well into the quasi-bulk regime, opening up possibilities for electric field manipulation. Expand
Voltage-controlled domain wall traps in ferromagnetic nanowires.
A voltage can generate non-volatile switching of magnetic properties at the nanoscale by modulating interfacial chemistry rather than charge density, and is exploited to demonstrate a prototype non-Volatile memory device in which voltage-controlled domain wall traps facilitate electrical bit selection in a magnetic nanowire register.

Electrolyte-gated magnetoelectric actuation: Phenomenology, materials, mechanisms, and prospective applications
Manipulation of the magnetic behavior of materials with voltage (i.e., magnetoelectric actuation) has become a topic of intense research during the last years. Apart from its obvious interest from aExpand
Suppression of Metal-Insulator Transition in VO2 by Electric Field–Induced Oxygen Vacancy Formation
It is found that electrolyte gating of epitaxial thin films of VO2 suppresses the metal-to-insulator transition and stabilizes the metallic phase to temperatures below 5 kelvin, even after the ionic liquid is completely removed. Expand
Voltage-Controlled ON-OFF Ferromagnetism at Room Temperature in a Single Metal Oxide Film.
This electric-field-induced atomic-scale reconfiguration process is compositionally, structurally, and magnetically reversible and self-sustained, since no oxygen source other than the Co3O4 itself is required, and could lead to electric- field-controlled device concepts for spintronics. Expand
