Deviations from the extended London model at high magnetic fields in YBa${}_2$Cu${}_3$O${}_7$

E. Campillo, M. Bartkowiak, R. Riyat +8

We report on the evolution with magnetic field and temperature of the vortex lattice (VL) in fully-oxygenated YBa2Cu3O7 as studied by time-of-flight small angle neutron scattering.…
