Spin excitations in the skyrmion host Cu2OSeO3

Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Jonathan White, Peter Babkevich, Ping Huang, Felix Groitl, Gregory Scott Tucker

We have used inelastic neutron scattering to measure the magnetic excitation spectrum along the high-symmetry directions of the first Brillouin zone of the magnetic skyrmion hosting compound Cu2OSeO3. The majority of our scattering data are consistent with ...

Magnetic Excitations and Electronic Interactions in Sr2CuTeO6: A Spin-1/2 Square Lattice Heisenberg Antiferromagnet

Henrik Moodysson Rønnow, Oleg Yazyev, Peter Babkevich, Vamshi Mohan Katukuri

Sr2CuTeO6 presents an opportunity for exploring low-dimensional magnetism on a square lattice of S = 1/2 Cu2+ ions. We employ ab initio multireference configuration interaction calculations to unravel the Cu2+ electronic structure and to evaluate exchange ...

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 ...

Spin wave excitations in the tetragonal double perovskite Sr2CuWO6

Sami Juhani Vasala

Sr2CuWO6 is a double perovskite proposed to be at the border between two- and three-dimensional magnetism, with a square lattice of S = 1/2 Cu2+ ions. We have used inelastic neutron scattering to investigate the spin wave excitations of the system, to find ...

Spiral magnetic phase in Li-doped Na2IrO3

Sándor Tóth, Kazimierz Conder

The doping of the honeycomb lattice compound Na2IrO3 with cations having smaller ionic radius such as lithium was supposed to drive the system into a Kitaev spin liquid phase. Even at the smallest doping level the long range magnetic order, present in the ...

Magnetic excitations in soft X-ray RIXS: Recent developments

Marco Grioni, Simon Karl Moser, Sara Fatale

Resonant inelastic X-ray scattering (RIXS) has rapidly become a mature spectroscopic technique. In particular, taking advantage of an improved energy resolution, a series of experiments performed over the past 5 years have established soft X-ray RIXS as a ...

Elsevier Science Bv2015

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 ...

Continuous Angular Multiple Energy Analysis Spectrometer Report on Instrument Concept and Scientific Case

Paul Gregory Freeman

Abstract This work unit proposes to construct a cold indirect geometry time of flight spectrometer for performing inelastic neutron scattering experiments optimized for optimal efficiency in the horizontal scattering plane at the European Spallation Source ...

We study the ligand-field splittings and magnetic properties of three Er-III single-ion magnets which differ in the peripheral ligand sphere but exhibit similar first coordination spheres by inelastic neutron scattering (INS) and SQUID magnetometry. The IN ...

Correlated Decay of Triplet Excitations in the Shastry-Sutherland Compound SrCu2(BO3)(2)

Henrik Moodysson Rønnow, Joël Mesot, Mohamed Zayed, Kazimierz Conder

The temperature dependence of the gapped triplet excitations (triplons) in the 2D Shastry-Sutherland quantum magnet SrCu2(BO3)(2) is studied by means of inelastic neutron scattering. The excitation amplitude rapidly decreases as a function of temperature, ...
