Reversible Magneto-ionic Modification of Metallic Magnetic Thin Films
Md Golam Hafiz, Hari Babu Vasili, Philippa Shepley +12
Magnetic multilayers with structural inversion asymmetry, perpendicular magnetic anisotropy (PMA), and large Dzyaloshinskii-Moriya interaction (DMI) are widely studied for magnetic…
Tuning the Electronic States of Bi2Se3 Films with Large Spin-Orbit Interaction Using Molecular Heterojunctions
Matthew Rogers, Craig Knox, Bryan Hickey +13
An electric bias can shift the Fermi level along the Dirac cone of a topological insulator and modify its charge transport, but tuning the electronic states and spin-orbit interact…
Tuning and Suppression of YIG Magnetisation Dynamics via Antiferromagnetic Interface Coupling
Oscar Cespedes, Hari B. Vasili, Matthew Rogers +4
The magnetisation dynamics of yttrium iron garnet (Y3Fe5O12, YIG) are key to the operation of spintronic and microwave devices. Here, we report a pathway to manipulate the frequenc…
Low-energy, ultrafast spin reorientation at competing hybrid interfaces with tunable operating temperature
Servet Ozdemir, Matthew Rogers, Jaka Strohsack +12
Information can be stored in magnetic materials by encoding with the direction of the magnetic moment of elements. A figure of merit for these systems is the energy needed to chang…

Orbital Occupancy and Hybridization in Strained SrVO Epitaxial Films
Mathieu Mirjolet, Hari Babu Vasili, Adrian Valadkhani +6
Oxygen packaging in transition metal oxides determines the metal-oxygen hybridization and electronic occupation at metal orbitals. Strontium vanadate (SrVO), having a single el…
Perovskite-type cobalt oxide at the multiferroic Co/Pb ZrTiO interface
K. Mohseni, A. Polyakov, H. B. Vasili +13
Magnetic Tunnel Junctions whose basic element consists of two ferromagnetic electrodes separated by an insulating non-magnetic barrier have become intensely studied and used in non…
Ubiquitous impact of localised impurity states on the exchange coupling mechanism in magnetic topological insulators
