Ultrafast generation of hidden phases via energy-tuned electronic photoexcitation in magnetite

Thomas La Grange, Fabrizio Carbone, Ivan Madan, Benoît Guilhem Michel Binh Truc, Francesco Pennacchio, Gabriele Berruto, Giovanni Maria Vanacore, Paolo Usai

Phase transitions occurring in nonequilibrium conditions can evolve through high-energy intermediate states inaccessible via equilibrium adiabatic conditions. Because of the subtle nature of such hidden phases, their direct observation is extremely challen ...

Revisiting the Excitation of the Low-Lying ^{181m}Ta Isomer in Optical Laser-Generated Plasma

Fabrizio Carbone, Ivan Madan, Benoît Guilhem Michel Binh Truc, Giovanni Maria Vanacore, Paolo Usai, Simone Gargiulo, Veronica Leccese

The excitation of the ^{181m}Ta isomer in the laser-plasma scenario was claimed to have been observed more than two decades ago. However, the reported experimental findings-and the respective high excitation rate-were later questioned as they could not be ...

Ultrafast control of emergent quantum matter probed by electron microscopy

Benoît Guilhem Michel Binh Truc

In the quest for controlling materials' properties, light as an external stimulus has a special place as it can create new states of matter and enable their ultrafast manipulation. In particular, spintronics, an exciting emergent field relying on the elect ...

Light-Induced Metastable Hidden Skyrmion Phase in the Mott Insulator Cu2OSeO3

Thomas La Grange, Arnaud Magrez, Henrik Moodysson Rønnow, Fabrizio Carbone, Ivan Madan, Benoît Guilhem Michel Binh Truc, Simone Gargiulo, Phoebe Marie Tengdin

The discovery of a novel long-lived metastable skyrmion phase in the multiferroic insulator Cu2OSeO3 visualized with Lorentz transmission electron microscopy for magnetic fields below the equilibrium skyrmion pocket is reported. This phase can be accessed ...

Synthesis and crystal structure of Fe[SeO4]OH and prediction of polytypes in the extended R[MO4]Z family

Arnaud Magrez, Alla Arakcheeva, Benoît Guilhem Michel Binh Truc

Single crystals of Fe[SeO4]OH have been synthesized by hydrothermal treatment. The Fe[SeO4]OH structure was investigated using the superspace approach. It is shown that the structure belongs to a family of compounds including kieserite-like and pauflerite- ...
