Degenerate ground state and anomalous flux hysteresis in an YBa2Cu3O7 grain boundary r.f. SQUID
C. H. Gardiner, R. A. M. Lee, J. C. Gallop +3
We report measurements of the flux hysteresis curves and trapped flux distribution in an YBa2Cu3O7 r.f. SQUID containing two closely spaced grain boundary Josephson junctions in pa…
Cooperative Jahn-Teller Distortion in PrO2
C. H. Gardiner, A. T. Boothroyd, P. Pattison +3
We report neutron diffraction data on single crystal PrO2 which reveal a cooperative Jahn-Teller distortion at TD = 120 +/- 2 K. Below this temperature an internal distortion of th…
Phonon Dispersion Relations in PrBa2Cu3O6+x (x ~ 0.2)
C. H. Gardiner, A. T. Boothroyd, B. H. Larsen +5
We report measurements of the phonon dispersion relations in non-superconducting, oxygen-deficient PrBa2Cu3O6+x (x ~ 0.2) by inelastic neutron scattering. The data are compared wit…
Localized 4f States and Dynamic Jahn-Teller Effect in PrO2
A. T. Boothroyd, C. H. Gardiner, S. J. S. Lister +6
Neutron spectroscopic measurements of the magnetic excitations in PrO reveal (1) sharp peaks characteristic of transitions between levels of the configuration of Pr$^{4+…
