Antiferromagnetic spin canting and Magnetoelectric Multipoles in h-YMnO
M. Ramakrishnan, Y. Joly, Q. N. Meier +7
Hexagonal YMnO is a prototype antiferromagnet which exhibits multiferroic behavior with the ferroelectric and magnetic transitions occurring at different temperatures. We obs…
Photoinduced structural dynamics of multiferroic TbMnO
Elsa Abreu, Matteo Savoini, Larissa Boie +17
We use time-resolved hard x-ray diffraction to investigate the structural dynamics of the multiferroic insulator TbMnO in the low temperature antiferromagnetic and ferroelectri…
Magnetic field dependent cycloidal rotation in pristine and Ge doped CoCrO
N Ortiz Hernandez, S Parchenko, J R L Mardegan +11
We report a soft x-ray resonant magnetic scattering study of the spin configuration in multiferroic thin films of CoGeCrO (Ge-CCO) and CoCrO (CC…
Structurally assisted melting of excitonic correlations in 1T-TiSe2
Max Burian, Michael Porer, Jose R. L. Mardegan +16
The simultaneous condensation of electronic and structural degrees of freedom gives rise to new states of matter, including superconductivity and charge-density-wave formation. Whe…
Correlation between electronic and structural orders in 1T-TiSe2
Hiroki Ueda, Michael Porer, José R. L. Mardegan +11
The correlation between electronic and crystal structures of 1T-TiSe2 in the charge density wave (CDW) state is studied by x-ray diffraction. Three families of reflections are used…
Ultrafast electron localization in a correlated metal
Jose R. L. Mardegan, Serhane Zerdane, Giulia Mancini +27
Ultrafast electron delocalization induced by a fs laser pulse is a well-known process and is the initial step for important applications such as fragmentation of molecules or laser…
Orbital dynamics during an ultrafast insulator to metal transition
Sergii Parchenko, Eugenio Paris, Daniel McNally +20
Phase transitions driven by ultrashort laser pulses have attracted interest both for understanding the fundamental physics of phase transitions and for potential new data storage o…
Dynamic pathway of the photoinduced phase transition of TbMnO
Elisabeth Bothschafter, Elsa Abreu, Laurenz Rettig +16
We investigate the demagnetization dynamics of the cycloidal and sinusoidal phases of multiferroic TbMnO by means of time-resolved resonant soft x-ray diffraction following exc…
