Phase-Coherent Spin and Lattice Modulations in a Y-type Hexaferrite
Oskar Stepančić, Annika Stellhorn, Emma Campillo +7
Spin-driven multiferroics owe their electric polarization to lattice distortions that follow the magnetic order, yet in incommensurate magnets symmetry normally forbids such a dist…
Experimental Limit on Neutron Orbital Angular Momentum Detection Using Polarized 3He
D. Sarenac, O. Lailey, D. V. Garrad +11
A recent proposal suggested that neutron orbital angular momentum (OAM) states could be detected via spin-polarized absorption in polarized 3He, with predicted cross-section variat…
Microscopic parameters of a type-II superconductor measured by small-angle neutron scattering
D. Alba Venero, A. -M. Valente-Feliciano, O. O. Bernal +1
A necessary condition for understanding and predicting the properties of any material is knowledge of microscopic parameters which control these properties in a state of thermodyna…
Incommensurate magnetic order drives singular angular magnetoresistance in a Weyl semimetal
X. Yao, P. Chen, R. Verma +15
We demonstrate that a multi- incommensurate magnetic state in the Weyl semimetal CeAlGe gives rise to singular angular magnetoresistance (SAMR), an electrical-transport…
Spin-disorder-induced angular anisotropy in polarized magnetic neutron scattering
I. Titov, M. Bersweiler, M. P. Adams +14
We experimentally report a hitherto unseen angular anisotropy in the polarized small-angle neutron scattering (SANS) cross section of a magnetically strongly inhomogeneous material…
Configuration of the magnetosome chain: a natural magnetic nanoarchitecture
I. Orue, L. Marcano, P. Bender +10
Magnetospirillum gryphiswaldense is a microorganism with the ability to biomineralize magnetite nanoparticles, called magnetosomes, and arrange them into a chain that behaves like…
Electric Field Controlled Mechanism for the Deflection of Skyrmions
Samuel H. Moody, Matthew T. Littlehales, Jonathan S. White +4
Magnetic skyrmions are vortex-like, swirls of magnetisation whose topological protection and particle-like nature have suggested them to be suitable for a number of novel spintroni…
Using small-angle scattering to guide functional magnetic nanoparticle design
Dirk Honecker, Mathias Bersweiler, Sergey Erokhin +8
Magnetic nanoparticles offer unique potential for various technological, biomedical, or environmental applications thanks to the size-, shape- and material-dependent tunability of…
Experimental Evidence of a change of Exchange Anisotropy Sign with Temperature in Zn-Substituted Cu2OSeO3
S. H. Moody, P. Nielsen, M. N. Wilson +4
We report small-angle neutron scattering from the conical state in a single crystal of Zn-substituted Cu2OSeO3. Using a 3D vector-field magnet to reorient the conical wavevector, o…
Pinning of Helimagnetic Phase Transitions in Zn-Substituted Skyrmion Host CuOSeO
M. T. Birch, S. H. Moody, M. N. Wilson +9
Magnetic skyrmions are nano-sized topological spin textures stabilized by a delicate balance of magnetic energy terms. The chemical substitution of the underlying crystal structure…
Oriented Three-Dimensional Magnetic Biskyrmion in MnNiGa Bulk Crystals
Xiyang Li, Shilei Zhang, Hang Li +10
A biskyrmion consists of two bound, topologically stable skyrmion spin textures. These coffee-bean-shaped objects have been observed in real-space in thin plates using Lorentz tran…
Thermally and field-driven mobility of emergent magnetic charges in square artificial spin ice
Sophie A. Morley, Jose Maria Porro, Aleš Hrabec +7
Designing and constructing model systems that embody the statistical mechanics of frustration is now possible using nanotechnology. We have arranged nanomagnets on a two-dimensiona…
Magnetization dynamics of weakly interacting sub-100 nm square artificial spin ices
Jose M. Porro, Sophie Morley, Diego Alba Venero +6
Artificial Spin Ice (ASI), consisting of a two dimensional array of nanoscale magnetic elements, provides a fascinating opportunity to observe the physics of out of equilibrium sys…
Vogel-Fulcher-Tammann Freezing of a Thermally Fluctuating Artificial Spin Ice Probed by X-ray Photon Correlation Spectroscopy
S. A. Morley, D. Alba Venero, J. M. Porro +6
We report on the crossover from the thermal to athermal regime of an artificial spin ice formed from a square array of magnetic islands whose lateral size, 30~nm~~70~nm, is…
