Hybrid magnets enable to achieve very high magnetic fields by combining resistive insert magnets with a large bore superconducting outer coil. In order to reduce the electromagnetic coupling between the coils, we introduce an eddy-current shield betw

A new superconducting coil outsert has been designed to be integrated within the existing infrastructure of the GHMFL hybrid project. Based on the novel development of a Nb-Ti Rutherford Cable On Conduit Conductor (RCOCC) cooled at 1.8 K by a bath of

The morphology of Condon domains in a plate-like sample is studied based on Shoenberg's assumption for the magnetic flux dependence of the diamagnetic moments which account for the instability of a correlated electron gas under the conditions of stro

In a framework of catastrophe theory we investigate the equilibrium set for an electron gas at the conditions of strong dHvA effect and show that discontinuities accompanied the diamagnetic phase transition (DPT) is handled by Riemann–Hugoniot cata

The temperature and magnetic field behavior of non-uniform diamagnetic phase in Be is analyzed theoretically. It is shown, that in the model of slightly corrugated cylinder-like Fermi surface sheet relevant for dHvA oscillations in Be, the parameters

Condon domains form when the de Haas-van Alphen (dHvA) amplitude becomes large compared to the dHvA period, i.e. μ0∂M/∂B > 1, where M is the magnetization and B the induction. This equation defines the boundary between the homogeneous magnetizat

The Grenoble High Magnetic Field Facility (GHMFL) is open to the international scientific community. It can produce steady magnetic fields on 3 magnet sites with a 24MW power supply and on 6 sites with 12 MW. One of the 24 MW sites is designed to rea

The nonlinear response to an ac magnetic field with and without parametric pumping was studied experimentally on a rod-like beryllium single crystal at low temperatures in a quantizing magnetic field applied parallel to the hexagonal axis. At low tem

The superconducting magnet for the Grenoble 40-T Hybrid system has been tested, up to its guaranteed value of 7 T, on its own and together with the resistive magnet. Although the superconducting magnet has been consistently operated at 7 T several ti

The distributions of magnetic field above the surface of the sample due to existence of the diamagnetic domain structure are found. It is shown, that the constant magnetic induction splitting inside of a sample is caused by the magnetization current
