Low temperature magnetic structure of geometrically frustrated SrHo2O4

Olga Young, Laurent C. Chapon, Oleg A. Petrenko

SrHo2O4 is a geometrically frustrated compound because the Ho^3+ ions are arranged in a network of triangles and hexagons and coupled with antiferromagnetic exchange interactions.…

Probing high-energy electronic excitations using inelastic neutron scattering

Young-June Kim, A. P. Sorini, C. Stock +3

High-energy, local multiplet excitations of the d-electrons are revealed in our inelastic neutron scattering measurements on the prototype magnetic insulator NiO. These become allo…

Dynamic fields in the partial magnetization plateau of Ca3Co2O6

P. J. Baker, J. S. Lord, D. Prabhakaran

Fluctuation dynamics in magnetization plateaux are a relatively poorly explored area in frustrated magnetism. Here we use muon spin relaxation to determine the fluctuation timescal…

Magnetic order in quasi-two-dimensional molecular magnets investigated with muon-spin relaxation

Andrew J. Steele, Tom Lancaster, Stephen J. Blundell +7

We present the results of a muon-spin relaxation (muSR) investigation into magnetic ordering in several families of layered quasi-two-dimensional molecular antiferromagnets based o…

Quantum criticality in an Ising chain: experimental evidence for emergent E8 symmetry

R. Coldea, D. A. Tennant, E. M. Wheeler +6

Quantum phase transitions take place between distinct phases of matter at zero temperature. Near the transition point, exotic quantum symmetries can emerge that govern the excitati…

Measurement of the internal magnetic field in the correlated iridates Ca $_{4}$ IrO $_{6}$ , Ca $_{5}$ Ir $_{3}$ O $_{12}$ , Sr $_{3}$ Ir $_{2}$ O $_{7}$ and Sr $_{2}$ IrO $_{4}$

I. Franke, P. J. Baker, S. J. Blundell +4

Oxides containing iridium ions display a range of magnetic and conducting properties that depend on the delicate balance between interactions and are controlled, at least in part,…

Low-moment magnetism in the double perovskites Ba2MOsO6 (M=Li,Na)

Andrew J. Steele, Peter J. Baker, Tom Lancaster +7

The magnetic ground states of the isostructural double perovskites Ba $_{2}$ NaOsO $_{6}$ and Ba $_{2}$ LiOsO $_{6}$ are investigated with muon-spin rotation. In Ba $_{2}$ NaOsO $_{6}$ long-range magne…

Molecular spin-orbit excitations in the J_eff = 1/2 frustrated spinel GeCo $_{2}$ O $_{4}$

K. Tomiyasu, M. K. Crawford, D. T. Adroja +9

We describe powder and single-crystal inelastic neutron scattering experiments on a spinel-type antiferromagnet GeCo $_{2}$ O $_{4}$ , represented by an effective total angular momentum J_…
