Strongly correlated quantum materials and magnetism
logo_tutelle logo_tutelle 

This scientific axis encompasses research activities on a large variety of magnetic and/or strongly correlated electron systems. Included are studies of unconventional superconductors (cuprates, pnictides), geometrically frustrated pyrochlore magnets (spin ices), novel magnetic orders in 4f-electron systems (heavy fermions, Kondo insulators), multiferroic compounds with interplay between electric and magnetic orders, manganites with giant magnetoresistance properties, and molecular magnets.

The techniques involved are neutron diffraction and inelastic neutron scattering, with the optional use of polarized neutrons.
