We study the directional excitation of optical surface waves controlled by the magnetic field of light. We theoretically predict that a spinning magnetic dipole develops a tunable unidirectional coupling of light to transverse electric (TE) polarized Bloch ...

Thermodynamic evidence of a second skyrmion lattice phase and tilted conical phase in Cu2OSeO3

Helmuth Berger

Precision measurements of the magnetization and ac susceptibility of Cu2OSeO3 are reported for magnetic fields along different crystallographic directions, focusing on the border between the conical and the field-polarized state for a magnetic field along ...

Magnetic Spin-Orbit Interaction of Light Steers Bloch Surface Waves

Hans Peter Herzig, Myun Sik Kim, Maria-Pilar Bernal, Huihui Lü

We show the directional excitation of Bloch surface waves controlled by the magnetic field of light. The phenomenon in play is the first magnetic spin-orbit interaction of light. It opens new degrees of freedom in the manipulation of light and offers appea ...

The challenge of one-dimensional systems is to understand their physics beyond the level of known elementary excitations. By high-resolution neutron spectroscopy in a quantum spin-ladder material, we probe the leading multiparticle excitation by characteri ...

Magnetic excitations from the two-dimensional interpenetrating Cu framework in Ba2Cu3O4Cl2

Henrik Moodysson Rønnow, Peter Babkevich, Diane Virginie Marie Lançon, Noore Elahi Shaik, Mechthild Enderle

We report detailed neutron scattering studies on Ba2Cu3O4Cl2. The compound consists of two interpenetrating sublattices of Cu, labeled as Cu-A and Cu-B, each of which forms a square-lattice Heisenberg antiferromagnet. The two sublattices order at different ...

Topological spin-hedgehog crystals of a chiral magnet as engineered with magnetic anisotropy

Henrik Moodysson Rønnow, Jonathan White

We report the engineering of spin-hedgehog crystals in thin films of the chiral magnet MnGe by tailoring the magnetic anisotropy. As evidenced by neutron scattering on films with different thicknesses and by varying a magnetic field, we can realize continu ...

Oriented O(3P2), Ne(3P2), and He(3S1) atoms emerging from a bent magnetic guide

Andreas Osterwalder, Justinas Jankunas

We describe our observation of strongly oriented total electronic angular momentum J in O(P-3(2)), Ne(P-3(2)), and He(S-3(1)) atoms emerging from a bent magnetic multipole guide, as measured by resonant multiphoton ionisation. This was contrary to our expe ...

Taylor & Francis2016

We performed inelastic neutron scattering measurements on single crystals of NdFe3((BO3)-B-11)(4) to explore the magnetic excitations, to establish the underlying Hamiltonian, and to reveal the detailed nature of hybridization between the 4f and 3d magneti ...

Spin-Relaxation Anisotropy in a GaAs Quantum Dot

Pasquale Scarlino

We report that the electron spin-relaxation time T1 in a GaAs quantum dot with a spin-1/2 ground state has a 180° periodicity in the orientation of the in-plane magnetic field. This periodicity has been predicted for circular dots as being due to the inter ...
