Magnetic phase diagram of multiferroic GdMn2O5
In the last five years, we have carried out a comprehensive study of the family of REMn2O5 multiferroics by neutron and X-ray magnetic scattering, providing details about the... -
Anomalously slow magnetic relaxation in a multi-q helimagnetic phase of SrFeO3
Non-coplanar magnetic orders in metallic helimagnets have been of great interest since the discovery of a vortex-like spin-swirling object called "skyrmion" and the resulting... -
Electric field effects on the spin correlation length in multiferroic delafos...
In a previous WISH experiment, we have succeeded in determining the incommensurate cycloidal magnetic structure of AgFeO2, which induces a ferroelectric polarization[1].... -
Investigation of Jahn-Teller assisted polaron collapse beyond the percolation...
Polaron-mediated colossal magneto-resistance (CMR) was predicted decades ago but never been experimentally established unambigously, despite the 'universal' existence of...
