Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-7 (2016)
In compounds containing 4f and 5f elements, hidden-order phases exist which are undetectable by many methods, the origins of which are debated. Here, the authors use photoemission and neutron scattering methods to show how such a multipolar-ordered p

Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-8 (2016)
Cu2OSeO3 possesses a helical spin structure which supports a rich phase diagram of magnetic states, including a lattice of particle-like skyrmions. Here, the authors use inelastic neutron scattering to elucidate the three-dimensional magnon spectrum

Field-Angle-Resolved Magnetic Excitations as a Probe of Hidden-Order Symmetry in CeB_{6}
Autor: P. Y. Portnichenko, A. Akbari, S. E. Nikitin, A. S. Cameron, A. V. Dukhnenko, V. B. Filipov, N. Yu. Shitsevalova, P. Čermák, I. Radelytskyi, A. Schneidewind, J. Ollivier, A. Podlesnyak, Z. Huesges, J. Xu, A. Ivanov, Y. Sidis, S. Petit, J.-M. Mignot, P. Thalmeier, D. S. Inosov
Publikováno v: Physical Review X, Vol 10, Iss 2, p 021010 (2020)
In contrast to magnetic order formed by electrons’ dipolar moments, ordering phenomena associated with higher-order multipoles (quadrupoles, octupoles, etc.) are more difficult to characterize because of the limited choice of experimental probes th

Pseudo-Goldstone Magnons in the Frustrated S=3/2 Heisenberg Helimagnet ZnCr_{2}Se_{4} with a Pyrochlore Magnetic Sublattice

Publikováno v: Physical Review X, Vol 7, Iss 4, p 041049 (2017)
Low-energy spin excitations in any long-range ordered magnetic system in the absence of magnetocrystalline anisotropy are gapless Goldstone modes emanating from the ordering wave vectors. In helimagnets, these modes hybridize into the so-called helim

Publikováno v: Photomask Technology 2021.
In this paper we introduce a method of combining the use of the KLA FlashScan® reticle blank defect inspection system and the KLA LMS IPRO reticle pattern registration metrology system for high-precision mask defect inspection and registration. We i

Local origin of the strong field-space anisotropy in the magnetic phase diagrams of Ce1−xLaxB6 measured in a rotating magnetic field

Publikováno v: Physical Review B. 103
Cubic $f$-electron compounds commonly exhibit highly anisotropic magnetic phase diagrams consisting of multiple long-range ordered phases. Field-driven metamagnetic transitions between them may depend not only on the magnitude, but also on the direct

We observe a hysteretic reorientation of the magnetic vortex lattice in the noncentrosymmetric superconductor ${\mathrm{Ru}}_{7}{\mathrm{B}}_{3}$, with the change in orientation driven by altering the magnetic field below ${T}_{\mathrm{c}}$. Normally
