Dynamics of photo-induced ferromagnetism in oxides with orbital degeneracy
Jonathan B. Curtis, Ankit Disa, Michael Fechner +2
By using intense coherent electromagnetic radiation, it may be possible to manipulate the properties of quantum materials very quickly, or even induce new and potentially useful ph…
Optical Stabilization of Fluctuating High Temperature Ferromagnetism in YTiO
A. S. Disa, J. Curtis, M. Fechner +9
In quantum materials, degeneracies and frustrated interactions can have a profound impact on the emergence of long-range order, often driving strong fluctuations that suppress func…
Probing photo-induced rearrangements in the NdNiO magnetic spiral with polarization-sensitive ultrafast resonant soft x-ray scattering
K. R. Beyerlein, A. S. Disa, M Först +10
We use resonant soft X-ray diffraction to track the photo-induced dynamics of the antiferromagnetic structure in a NdNiO thin film. Femtosecond laser pulses with a photon ene…
Disentangling lattice and electronic contributions to the metal-insulator transition from bulk vs. layer confined RNiO
Alexandru B. Georgescu, Oleg E. Peil, Ankit Disa +2
In complex oxide materials, changes in electronic properties are often associated with changes in crystal structure, raising the question of the relative roles of the electronic an…
Control of hidden ground-state order in NdNiO superlattices
Ankit S. Disa, Alexandru B. Georgescu, James L. Hart +8
The combination of charge and spin degrees of freedom with electronic correlations in condensed matter systems leads to a rich array of phenomena, such as magnetism, superconductiv…
Structural Distortions At Polar Manganite Interfaces
S. Koohfar, A. S. Disa, M. Marshall +3
Electronic, lattice, and spin interactions at the interfaces between crystalline complex transition metal oxides can give rise to a wide range of functional electronic and magnetic…
