Electric Field Effects in the Skyrmion Lattice Hosting Magnet Cu2OSeO3

Magnetic skyrmions have garnered much attention in recent years because of their non trivial topology and potential to be used in next generation memory devices. They may exist individually or as a lattice of skyrmions(SkL). A number of investigations have ...

Spiral spin-liquid and the emergence of a vortex-like state in MnSc2S4

Jonathan White, Gregory Scott Tucker, Romain Sibille, Shang Gao

Spirals and helices are common motifs of long-range order in magnetic solids, and they may also be organized into more complex emergent structures such as magnetic skyrmions and vortices. A new type of spiral state, the spiral spin-liquid, in which spins f ...

Characterization of Ligand Shell for Mixed-Ligand Coated Gold Nanoparticles

Francesco Stellacci, Quy Ong Khac, Zhi Luo

Gold nanoparticles owe a large number of their properties to their ligand shell. Indeed, many researchers routinely use mixtures of ligand molecules for their nanoparticles to impart complex property sets. It has been shown that the morphology of ligand sh ...

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 ...

Neutron spectroscopy in the layered quantum magnet SrCu₂(BO₃)₂ and in transition metal phosphorus trisulfides (MPS₃)

Diane Virginie Marie Lançon

Collective magnetic excitations are a fascinating aspect of condensed matter physics, where neutron scattering can provide valuable insight into the magnetic properties of physical realisations of model systems. This thesis focuses on the excitation spectr ...

Control of Topological Magnetic Textures by Magnetic and Electric Fields in Magnetoelectric Helimagnet Cu₂OSeO₃

Ping Huang

Magnetic skyrmions, topologically non-trivial chiral whirl-like spin configurations, have been under massive investigations in both fundamental and application aspects. In some special compounds, these quasi-particles can formtriangular skrymion lattice (S ...

A combined radial collimator and cooled beryllium filter for neutron scattering

Henrik Moodysson Rønnow, Felix Groitl

A flexible, combined, radial collimator and beryllium (Be) filter have been designed and manufactured at the Paul Scherrer Institut (PSI), Switzerland. The Be is integrated in the radial collimator by placing thin Be slices between the collimator lamellas. ...

Direct observation of anisotropic magnetic field response of the spin helix in FeGe thin films

Henrik Moodysson Rønnow, Jonathan White

We report the observation by small-angle neutron scattering (SANS) of a magnetic helical structure confined in a thin film of the chiral lattice magnet FeGe. Twofold magnetic Bragg spots appearing below the magnetic transition temperature indicate the form ...

Magnetic structure and magnon dynamics of the quasi-two-dimensional antiferromagnet FePS3

Henrik Moodysson Rønnow, Diane Virginie Marie Lançon

Neutron scattering from single crystals has been used to determine the magnetic structure and magnon dynamics of FePS3, an S = 2 Ising-like quasi-two-dimensional antiferromagnet with a honeycomb lattice. The magnetic structure has been confirmed to have a ...

X‑ray and Neutron Scattering of Water

Livia Eleonora Bove Kado

This review article focuses on the most recent advances in X-ray and neutron scattering studies of water structure, from ambient temperature to the deeply supercooled and amorphous states, and of water diffusive and collective dynamics, in disparate thermo ...
