Unidirectional information flow in a nanomagnetic metamaterial
Johannes H. Jensen, Ida Breivik, Arthur Penty +10
Artificial spin ice (ASI) are metamaterials composed of interacting nanomagnets. Although ASI hold promise for low-power computing, the ability to transmit information through thes…
Magnetic Circular Dichroism at the Oxygen K edge in Microcrystals of Spinels Grown on Ru(0001)
A. Mandziak, V. Sosa, P. Nita +10
We have measured the circular magnetic dichroism in the x-ray absorption at the K-edge of oxygen in microcrystals of different spinel oxides. The microcrystals are islands of micro…
Voltage-Controlled Rotation of Magnetic Anisotropy in the Ni90Fe10/BaTiO3(001) Heterostructure
A. Begué, M. W. Khaliq, N. Cotón +4
In this work, we demonstrate the voltage control of magnetic anisotropy in a strain-mediated Ni90Fe10/BaTiO3(001) heterostructure. In the pristine state of the heterostructure, the…
Magnetoacoustic waves in a highly magnetostrictive FeGa thin film
Marc Rovirola, M. Waqas Khaliq, Blai Casals +11
The interaction between surface acoustic waves and magnetization offers an efficient route for electrically controlling magnetic states. Here, we demonstrate the excitation of magn…
Magnetization patterns in - core-shell nanorods
Anastasiia Korniienko, Alexis Wartelle, Matthias Kronseder +8
We present a study on the static magnetic properties of individual - core-shell nanorods. X-ray Magnetic Circular Dichroism…
Moving magnetic domain walls with sound alone
Alejandro Rivelles, Rocío Yanes, Luis Torres +18
Surface Acoustic Waves (SAW) have been used in spintronic applications to decrease the magnetic field or the electric current required to act on the magnetization. A common belief…
Tailoring the energy landscape of a Bloch point singularity with curvature
Sandra Ruiz-Gomez, Claas Abert, Pamela Morales-Fernández +14
Topological defects, or singularities, play a key role in the statics and dynamics of complex systems. In magnetism, Bloch point singularities represent point defects that mediate…
Reversible out-of-plane to in-plane magnetic transition by electrical and thermal cycling in NiFe/BaTiO(001)
Adrián Begué, Muhammad Waqas Khaliq, Noelia Cotón +4
The study investigates the manipulation of the magnetic anisotropy in a thick (1 m) NiFe layer electrodeposited on a ferroelectric BaTiO(001) substrate, using…
Study of the magnetoelastic effect in nickel and cobalt thin films at GHz range using X-ray microscopy
Marc Rovirola, Muhammad Waqas Khaliq, Travis Gustafson +9
We use surface acoustic waves of 1 and 3 GHz in hybrid piezoelectric-magnetic systems with either cobalt or nickel as a magnetic layer to generate magnetoacoustic waves and directl…
Magneto-Acoustic Waves in antiferromagnetic CuMnAs excited by Surface Acoustic Waves
M. Waqas Khaliq, Oliver Amin, Alberto Hernández-Mínguez +15
Magnetoelastic effects in antiferromagnetic CuMnAs are investigated by applying dynamic strain in the 0.01% range through surface acoustic waves in the GaAs substrate. The magnetic…
Epitaxial monolayers of magnetic 2D semiconductor FeBr grown on Au(111)
S. E. Hadjadj, C. González-Orellana, J. Lawrence +20
Magnetic two-dimensional (2D) semiconductors have attracted a lot of attention because modern preparation techniques are capable of providing single crystal films of these material…
Franckeite: a naturally occurring van der Waals heterostructure
Aday J. Molina-Mendoza, Emerson Giovanelli, Wendel S. Paz +11
The fabrication of van der Waals heterostructures, artificial materials assembled by individually stacking atomically thin (2D) materials, is one of the most promising directions i…
