Patterning of sodium ions and the control of electrons in sodium cobaltate
M. Roger, D. J. P. Morris, D. A. Tennant +10
NaxCoO2 has emerged as a material of exceptional scientific interest due to the potential for thermoelectric applications, and because the strong interplay between the magnetic and…
Thermodynamic and magnetic properties of the layered triangular magnet NaNiO2
P. J. Baker, T. Lancaster, S. J. Blundell +4
We report muon-spin rotation, heat capacity, magnetization, and ac magnetic susceptibility measurements of the layered spin-1/2 antiferromagnet NaNiO2. These show the onset of long…
Unconventional magnetic properties of the weakly ferromagnetic metal BaIrO_3
M. L. Brooks, S. J. Blundell, T. Lancaster +4
We present experimental evidence for small-moment magnetism below the ferromagnetic transition temperature (T_c3 = 183 K) in the quasi-one-dimensional metal BaIrO_3. Further, we id…
Localized excitation in the hybridization gap in YbAl3
A. D. Christianson, J. M. Lawrence, E. A. Goremychkin +6
The intermediate valence compound YbAl3 exhibits a broad magnetic excitation with characteristic energy E1 ~ 50meV, of order of the Kondo energy (TK ~ 600-700K). In the low tempera…
Neutron scattering studies of the spin ices Ho2Ti2O7 and Dy2Ti2O7 in applied magnetic field
T. Fennell, O. A. Petrenko, B. Fak +3
Neutron diffraction has been used to investigate the magnetic correlations in single crystals of the spin ice materials Ho2Ti2O7 and Dy2Ti2O7 in an external magnetic field applied…
Quantum criticality and universal scaling of a quantum antiferromagnet
B. Lake, D. A. Tennant, C. D. Frost +1
Quantum effects dominate the behaviour of many diverse materials. Of particular current interest are those systems in the vicinity of a quantum critical point (QCP). Their physical…
