Reibelt, M; Weyeneth, S; Erb, A; Schilling, A (2011). Observation of a first-order phase transition deep within the vortex-solid region of YBa2Cu3O7. Superconductor Science and Technology, 24(10):105019.
We have investigated the magnetic phase diagram of a fully oxygenated detwinned YBa2Cu3O7 single crystal by means of magneto-caloric and magnetization measurements, and found thermodynamic evidence for a temperature dependent first-order phase-transition line deep within the vortex-solid region. The associated discontinuities in the entropy are apparently proportional to the magnetic flux density, which may hint at a structural transition of the vortex lattice.
