Nonlinear Hall effect in Weyl semimetals induced by chiral anomaly
Rui-Hao Li, Olle G. Heinonen, Anton A. Burkov +1
We predict a nonlinear Hall effect in certain Weyl semimetals with broken inversion symmetry. When the energy dispersions about pairs of Weyl nodes are skewed -- the Weyl cones are…
Inverse Design of a Graphene-Based Quantum Transducer via Neuroevolution
Kevin Ryczko, Pierre Darancet, Isaac Tamblyn
We introduce an inverse design framework based on artificial neural networks, genetic algorithms, and tight-binding calculations, capable to optimize the very large configuration s…
Dynamics of reconfigurable artificial spin ice: towards magnonic functional materials
Sebastian Gliga, Ezio Iacocca, Olle G. Heinonen
Over the past few years, the study of magnetization dynamics in artificial spin ices has become a vibrant field of study. Artificial spin ices are ensembles of geometrically arrang…
Tailoring spin wave channels in a reconfigurable artificial spin ice
Ezio Iacocca, Sebastian Gliga, Olle Heinonen
Artificial spin ices are ensembles of geometrically-arranged, interacting nanomagnets which have shown promising potential for the realization of reconfigurable magnonic crystals.…
Spin-to-charge conversion in magnetic Weyl semimetals
Steven S. -L. Zhang, Anton A. Burkov, Ivar Martin +1
Weyl semimetals (WSMs) are a newly discovered class of quantum materials which can host a number of exotic bulk transport properties, such as the chiral magnetic effect, negative m…
Topological Hall effect in diffusive ferromagnetic thin films with spin-flip scattering
Steven S. -L. Zhang, Olle Heinonen
We study the topological Hall effect in a diffusive ferromagnetic metal thin film by solving a Boltzmann transport equation in the presence of spin-flip scattering. A generalized s…
Tunable mode coupling in nano-contact spin torque oscillators
Steven S. -L. Zhang, Ezio Iacocca, Olle Heinonen
Recent experiments on spin torque oscillators have revealed interactions between multiple magnetodynamic modes, including mode-coexistence, mode-hopping, and temperature-driven cro…
Topologically non-trivial magnon bands in artificial square spin ices subject to Dzyaloshinskii-Moriya interaction
Ezio Iacocca, Olle Heinonen
Systems that exhibit topologically protected edge states are interesting both from a fundamental point of view as well as for potential applications, the latter because of the abse…
Direct Observation of the Skyrmion Hall Effect
Wanjun Jiang, Xichao Zhang, Guoqiang Yu +8
The well-known Hall effect describes the transverse deflection of charged particles (electrons or holes) in an electric-current carrying conductor under the influence of perpendicu…
The effect of Ta oxygen scavenger layer on HfO-based resistive switching behavior: thermodynamic stability, electronic structure, and low-bias transport
X. Zhong, I. Rungger, P. Zapol +3
Reversible resistive switching between high-resistance and low-resistance states in metal-oxide-metal heterostructures makes them very interesting for applications in random access…
Dynamic response of an artificial square spin ice
M. B. Jungfleisch, W. Zhang, E. Iacocca +9
Magnetization dynamics in an artificial square spin-ice lattice made of Ni80Fe20 with magnetic field applied in the lattice plane is investigated by broadband ferromagnetic resonan…
Generation of magnetic skyrmion bubbles by inhomogeneous spin Hall currents
Olle Heinonen, Wanjun Jiang, Hamoud Somaily +2
Recent experiments have shown that magnetic skyrmion bubbles can be generated and injected at room temperature in thin films [W. Jiang et al, Science vol. 349, 283 (2015)]. Here, w…
Reconfigurable spin wave band structure of artificial square spin ice
Ezio Iacocca, Sebastian Gliga, Robert L. Stamps +1
Artificial square spin ices are structures composed of magnetic elements arranged on a geometrically frustrated lattice and located on the sites of a two-dimensional square lattice…
