Neutron spectroscopic methods are indispensable tools to study dynamical processes such as diffusion, magnetic excitations and even electronic excitations.
The small signal size and the flux limitation of neutron sources result in long counting times. Moreover, the requirement of special sample environment to perform spectroscopic studies at extreme conditions affects the signal to noise ratio...

Soon after their discovery at the end of the 80’s, Cuprate High Temperature Superconductors (HTS) were expected to trigger a revolution in high field magnets thanks to their extremely high irreversibility field at low temperature. The difficulty to make these brittle ceramics into practical conductors led to a 20 years delay, with the first significant high field HTS magnet prototypes...

17. Stroboscopic polarized experiments to study the domain dynamics in multiferroics

In so-called type-II multiferroics, a complex magnetic structure of chiral character directly drives finite ferroelectric polarization resulting in a close coupling between magnetic and electric order parameters. Therefore, multiferroics allow one to fully control antiferromagnetic domains by external electric fields opening the path to the study of the corresponding domain dynamics. We use a...
