The crystal and magnetic structure of cesium superoxide
R. A. Ewings, M. Reehuis, F. Orlandi +7
CsO2 is a member of the family of alkali superoxides (formula AO2 with A= Na, K, Rb and Cs) that exhibit magnetic behavior arising from open -shell electrons residing on O2- mol…
Magnetically induced metal-insulator transition in Pb2CaOsO6
Henrik Jacobsen, Hai L. Feng, Andrew J. Princep +14
We report on the structural, magnetic, and electronic properties of two new double-perovskites synthesized under high pressure; Pb2CaOsO6 and Pb2ZnOsO6. Upon cooling below 80 K, Pb…
Magnetically driven loss of centrosymmetry in metallic Pb2CoOsO6
A. J. Princep, H. L. Feng, Y. F. Guo +11
We report magnetic, transport, neutron diffraction, and muon spin rotation data showing that PbCoOsO, a newly synthesized metallic double-perovskite with a centrosymmetric…
Evidence for ground state and defect-induced spin glass behaviour in the pyrochlore osmate YOsO
N. R. Davies, C. V. Topping, H. Jacobsen +14
We present AC and DC magnetometry, heat capacity, muon spin relaxation (SR) and resonant inelastic X-ray scattering (RIXS) studies of the pyrochlore osmate YOsO. We…
Spin dynamics and exchange interactions in CuO measured by neutron scattering
H. Jacobsen, S. M. Gaw, A. J. Princep +7
The magnetic properties of CuO encompass several contemporary themes in condensed matter physics, including quantum magnetism, magnetic frustration, magnetically-induced ferroelect…
The Final Chapter In The Saga Of YIG
A. J. Princep, R. A. Ewings, S. Ward +4
The magnetic insulator Yttrium Iron Garnet can be grown with exceptional quality, has a ferrimagnetic transition temperature of nearly 600 K, and is used in microwave and spintroni…
Covalency and vibronic couplings make a nonmagnetic j=3/2 ion magnetic
Lei Xu, Nikolay A. Bogdanov, Andrew Princep +3
For 4 and 5 spin-orbit-coupled electron configurations, the notion of nonmagnetic j=3/2 quartet ground state discussed in classical textbooks is at odds with the observed…
Commensurate lattice distortion in the layered titanium oxypnictides NaTiO ( As, Sb) determined by X-ray diffraction
N. R. Davies, R. D. Johnson, A. J. Princep +12
We report single crystal X-ray diffraction measurements on NaTiO ( = As, Sb) which reveal a charge superstructure that appears below the density wave transition…
Crystal field states in a Quantum Spin Ice]{Crystal field states of Pr in the candidate quantum spin ice PrSnO
A. J. Princep, D. Prabhakaran, A. T. Boothroyd +1
Neutron time-of-flight spectroscopy has been employed to study the crystal-field splitting of Pr in the pyrochlore stannate PrSnO. The crystal field has be…
High-order Ho multipoles in HoB2C2 observed with soft resonant x-ray diffraction
A. J. Princep, A. M. Mulders, E. Schierle +7
Soft resonant x-ray Bragg diffraction (SRXD) at the Ho M edges has been used to study Ho multipoles in the combined magnetic and orbitally ordered phase of HoBC$_2…
Triakontadipole and high-order dysprosium multipoles in the antiferromagnetic phase of DyBC
A. J. Princep, A. M. Mulders, U. Staub +5
Resonant soft x-ray Bragg diffraction at the Dy M edges has been used to study Dy multipoles in the combined magnetic and orbitally ordered phase of DyBC. The analy…
