Square vortex lattice at anomalously low magnetic fields in electron-doped NdCeCuO
R. Gilardi, J. Mesot, S. P. Brown +7
We report here on the first direct observations of the vortex lattice in the bulk of electron-doped NdCeCuO single crystals. Using small angle neutron scatt…

Observation of a Triangular to Square Flux Lattice Phase Transition in YBCO
S. P. Brown, D. Charalambous, E. C. Jones +3
We have used the technique of small-angle neutron scattering to observe magnetic flux lines directly in an YBCO single crystal at fields higher than previously reported. For field…

A small angle neutron scattering study of the vortex matter in La{2-x}Sr{x}CuO{4} (x=0.17)
R. Gilardi, S. Streule, A. J. Drew +7
The magnetic phase diagram of slightly overdoped La{2-x}Sr{x}CuO{4} (x=0.17) is characterised by a field-induced hexagonal to square transition of the vortex lattice at low fields…
