Destructive Interference of a Charge Density Wave in the Skyrmion Magnet GdRu2Si2
G. D. A. Wood, D. A. Mayoh, F. Orlandi +10
In skyrmion magnets, charge density waves induce higher-order exchange interactions that can select multi-Q ground states. Using resonant X-ray scattering and neutron diffraction,…
Weyl metallic state induced by helical magnetic order
Jian-Rui Soh, Irián Sánchez-Ramírez, Xupeng Yang +15
In the rapidly expanding field of topological materials there is growing interest in systems whose topological electronic band features can be induced or controlled by magnetism. M…
Competing charge and magnetic order in the candidate centrosymmetric skyrmion host EuGaAl
A. M. Vibhakar, D. D. Khalyavin, J. M. Moya +5
Eu(GaAl) are centrosymmetric systems that have recently been identified as candidates to stabilise topologically non-trivial magnetic phases, such as skyrmion latti…
Tuning magnetoelectricity in a mixed-anisotropy antiferromagnet
Ellen Fogh, Bastian Klemke, Manfred Reehuis +20
Control of magnetization and electric polarization is attractive in relation to tailoring materials for data storage and devices such as sensors or antennae. In magnetoelectric mat…
Precise control of magnetic properties in SrIrO epitaxial thin films by variation of strain and thin film thickness
Stephan Geprägs, Björn Erik Skovdal, Monika Scheufele +11
We report on a comprehensive investigation of the effects of strain and film thickness on the structural and magnetic properties of epitaxial thin films of the prototypal $J_\mathr…
Colossal magnetoresistance in a nonsymmorphic antiferromagnetic insulator
P. F. S. Rosa, Yuanfeng Xu, S. K. Kushwaha +14
Here we investigate antiferromagnetic EuInSb, a nonsymmorphic Zintl phase. Our electrical transport data show that EuInSb is remarkably insulati…
Spin-wave gap collapse in Rh-doped Sr2IrO4
J. Bertinshaw, J. K. Kim, J. Porras +7
We use resonant inelastic x-ray scattering (RIXS) at the Ir L3 edge to study the effect of hole doping upon the Jeff=1/2 Mott-insulating state in Sr2IrO4, via Rh replacement of the…
Stable hump-like Hall effect and non-coplanar spin textures in SrRuO ultrathin film
Byungmin Sohn, Bongju Kim, Se Young Park +11
We observed a hump-like feature in Hall effects of SrRuO ultrathin films, and systematically investigated it with controlling thicknesses, temperatures and magnetic fields. The…
Strain engineering a multiferroic monodomain in thin-film BiFeO
N. Waterfield Price, A. M. Vibhakar, R. D. Johnson +6
The presence of domains in ferroic materials can negatively affect their macroscopic properties and hence their usefulness in device applications. From an experimental perspective,…
Magnetic Anisotropy and Orbital Ordering in CaRuO
D. G. Porter, V. Granata, F. Forte +5
We review the magnetic and orbital ordered states in \cro{} by performing Resonant Elastic X-ray Scattering (REXS) at the Ru L-edges. In principle, the point symmetry at Ru…
Manifolds of magnetic ordered states and excitations in the almost Heisenberg pyrochlore antiferromagnet MgCr2O4
S. Gao, K. Guratinder, V. Tsurkan +18
In spinels ACr2O4 (A=Mg, Zn) realisation of the classical pyrochlore Heisenberg antiferromagnet model is complicated by a strong spin-lattice coupling: the extensive degeneracy of…
Modulated spin helicity stabilized by incommensurate orbital density waves in a quadruple perovskite manganite
R. D. Johnson, D. D. Khalyavin, P. Manuel +4
Through a combination of neutron diffraction and Landau theory we describe the spin ordering in the ground state of the quadruple perovskite manganite CaMn7O12 - a magnetic multife…
Non-coplanar and counter-rotating incommensurate magnetic order stabilized by Kitaev interactions in -Li2IrO3
A. Biffin, R. D. Johnson, I. Kimchi +5
Materials that realize Kitaev spin models with bond-dependent anisotropic interactions have long been searched for, as the resulting frustration effects are predicted to stabilize…
Cu3Nb2O8: a multiferroic with chiral coupling to the crystal structure
R. D. Johnson, Sunil Nair, L. C. Chapon +5
By combining bulk properties, neutron diffraction and non-resonant X-ray diffraction measurements, we demonstrate that the new multiferroic CuNbO becomes polar simultan…
Resonant X-ray scattering investigation of the multipolar ordering in Ca3Co2O6
A. Bombardi, C. Mazzoli, S. Agrestini +1
We have performed a resonant x-ray scattering (RXS) study near the Co K edge on a single crystal of Ca3Co2O6. In the magnetically ordered phase a new class of weak reflections appe…
Observation of local chiral-symmetry breaking in globally centrosymmetric crystals
S. Di Matteo, Y. Joly, A. Bombardi +3
A thorough tensor analysis of the Bragg-forbidden reflection (00.3) in corundum systems having a global center of inversion, like VO and -FeO, shows that ano…
