Locally induced laminar convection in liquid nitrogen and silicone oils
We present an experimental study of a laminar convective phenomenon induced by a centimetric heater totally immersed in a liquid pool (Rayleigh number ranging from 104 to 107). This local heating is observed to i...

Magnetocaloric effect in nano- and polycrystalline manganite La0.7Ca0.3MnO3
La0.7Ca0.3MnO3 samples were prepared in nano- and polycrystalline forms by the sol–gel and solid state reaction methods, respectively, and structurally characterized by synchrotron X-ray diffraction. The magnetic...

Magneto-transport characterization of Dy123 monodomain superconductors
We consider textured materials of the DyBa2Cu3O7 type seeded with a Nd123 seed as initiator. They are grown with an excess 20% Dy211 phase on a Dy2O3 substrate. We report chemical characterization, electrical res...
