Anomalous spin-triplet current in Ho/Co/Ho-based Josephson junctions

Published in Europhysics Letters, 2014

The supercurrent through a holmium/cobalt/holmium-based Josephson junction is investigated by using the extended the Blonder-Tinkham-Klapwijk (BTK) approach.

Plasticity of Persistent Photoconductance of Amorphous LaAlO3/SrTiO3Interfaces under Varying Illumination Conditions

Published in ACS Appl. Electron. Mater., 2019

At the interface between amorphous LaAlO3 films and SrTiO3 crystals Persistent photoconductance (PPC) is plastically modulated by optical stimuli of varying strength and duration, demonstrating fine-tuned photoconductive responsivity over a diversity of cumulated timespans.

Solid-State Synapses Modulated by Wavelength-Sensitive Temporal Correlations in Optic Sensory Inputs

Published in ACS Appl. Electron. Mater., 2019

Here we show a solid-state system that is sensitive to 100 ms-scale timing of pairs of light stimuli with complementary short/long visible wavelengths, causing asymmetric changes of photoconductance. We suggest that this capability may stimulate neuromorphic hybrid electronic/photonic systems to construct biomimetic spatial memory and navigation maps inspired from neurobiology.

Photoinduced Persistent Electron Accumulation and Depletion in LaAlO3/SrTiO3 Quantum Wells

Published in Physical Review Letters, 2020

We present the quantum well at the LaAlO3/SrTiO3 interface, where in addition to photoinduced accumulation, a secondary photoexcitation enables carrier depletion. The balance between both processes is wavelength dependent, and allows tunable accumulation or depletion in an asymmetric manner, depending on the relative arrival time of photons of different frequencies.

Mechanical, magnetic and magnetostrictive properties of porous Fe-Ga films prepared by electrodeposition

Published in Materials and Design, 2021

Fe-Ga films with variable composition and porosity levels are electro deposited.Both hardness and Young’s modulus decrease as the porosity degree increases.Highly tunable magnetic properties are achieved by adjusting the microstructure.Macroporous films show larger magnetic-field-induced crystal lattice deformation.

Magneto-ionic suppression of magnetic vortices

Published in Science and Technology of Advanced Materials, 2021

A novel magneto-ionic effect is demonstrated: the transition from vortex to coherent rotation states, caused by voltage-induced ion motion, in arrays of patterned nanopillars. Electrolyte-gated Co/GdOx bilayered nanopillars are chosen as a model system.

Ferromagnetic Quasi-Two-Dimensional Electron Gas with Trigonal Crystal Field Splitting

Orbital selective switching of ferromagnetism in an oxide quasi two-dimensional electron gas

Published in npj quantum materials, 2022

By using density functional theory calculations, transport, magnetic and x-ray spectroscopy measurements, we find that the filling of titanium-bands with 3dxz/3dyz orbital character in the EuTiO3 layer and at the interface with SrTiO3 induces an antiferromagnetic to ferromagnetic switching of the exchange interaction between Eu-4f7 magnetic moments.
