R.F. sputtering equipment. This multi-target RF sputtering is built from a Nordiko equipment, with a customized user interface. It uses a reactive plasma (Ar/O2) and a magnetron. It is used to grow oxides thin films, like cuprates or iridates.


We develop and use light experimental setups, allowing for the study of the electronic properties of our samples : conventional longitudinal and Hall transport, thermoelectric effect, surface sheet resistance, magnetization ...

Point contact spectroscopy is performed using either a mechanical contact from a metal tip, or a gold electrode deposited on the film.
A metallic tip, attached to a piezo fork used as a force sensor.

60 muM Hall probe array, manufactured by V. Mosser (Schlumberger), designed in collaboration with M. Konczykowski in Ecole Polytechnique.

This home made thermoelectric setup allows for measurements of thin films, from ambient down to 3 K.

This microtorquemeter is built from a commercial silicon piezo-resistive tip, originally designed for atomic force microscopy. It allows for the measurement of torque on very small samples, such as single crystals, typically a few dizains of micrometers. The setup can be inserted in a 7 T horizontal magnet. As an example is shown the first measurement of the equilibrium torque exerted on a YBaCuO single crystal, arising from heavy ions irradiation tracks.

This ’Fiory-like’ setup measures the transmission of an ac magnetic field through a thin film, allowing for the determination of the superconducting penetration depth and its temperature dependence.
