Role of defects in determining the magnetic ground state of ytterbium titanate
D. F. Bowman, E. Cemal, T. Lehner +11
Pyrochlore systems are ideally suited to the exploration of geometrical frustration in three dimensions, and their rich phenomenology encompasses topological order and fractional e…
Kagome modes, a new route to ultralow thermal conductivity?
D. J. Voneshen, M. Ciomaga Hatnean, T. G. Perring +4
From next generation gas turbines to scavenging waste heat from car exhausts, finding new materials with ultra-low thermal conductivity () has the potential to lead to large gai…
Linarite - a quasi-critical J-J chain
Eron Cemal, Mechthild Enderle, Reinhard K. Kremer +5
The mineral linarite, PbCuSO(OH), is a spin 1/2 chain with frustrating nearest neighbor ferromagnetic and next-nearest neighbor antiferromagnetic exchange interactions. Our…
Vacancy defects and monopole dynamics in oxygen-deficient pyrochlores
G. Sala, M. J. Gutmann, D. Prabhakaran +6
The idea of magnetic monopoles in spin ice has enjoyed much success at intermediate temperatures, but at low temperatures a description in terms of monopole dynamics alone is insuf…
Divacancy superstructures in thermoelectric calcium-doped sodium cobaltate
D. G. Porter, M. Roger, M. J. Gutmann +5
We have grown single crystals of NaCaCoO and determined their superstructures as a function of composition using neutron and x-ray diffraction. Inclusion of Ca s…
Two-dimensional Cs-vacancy superstructure in iron-based superconductor
D. G. Porter, E. Cemal, D. J. Voneshen +8
Single crystal neutron diffraction is combined with synchrotron x-ray scattering to identify the different superlattice phases present in . A combination of s…
