Reviving a hidden family of ferroelectrics through epitaxy
For decades, ferroelectric materials with complex layered structures were thought too difficult to grow with the quality needed for device applications. Among them is the ...
True amplification of spin waves in magnonic nano-waveguides
Magnonic nano-devices exploit magnons - quanta of spin waves - to transmit and process information within a single integrated platform that has the potential to outperform traditional semiconductor-based electronics.
Unravelling the key aspects for the reliable synthesis of superconducting nickelates
Scientists have successfully modulated magnetic information using electrical pulses while converting it into a polarized light signal. This discovery, described in the journal Nature, could revolutionize long-distance optical telecommunications.

Disentangling Photodoping, Photoconductivity, and Photosuperconductivity in the Cuprates
In superconducting materials, the electric current flows without energy dissipation (zero electrical resistance). This happens only below a so-called critical temperature Tc. The cuprates are ...
Emission of coherent THz magnons in an antiferromagnetic insulator triggered by ultrafast spin–phonon interactions
Free-space THz emission resulting from the femtosecond demagnetization of a spintronic THz emitter, and the subsequent spin-charge conversion in high spin-orbit material, has recently been ...
A multiferroic 2-dimensional electron gas
Multiferroics are a family of materials in which two properties that do not usually go together coexist: magnetism and ferroelectricity. Magnetism occurs naturally in some ...
An Oxygen Vacancy Memristor Ruled by Electron Correlations
Featuring in Advanced Science, our recent work demonstrates memristive switching effects produced by a redox-driven oxygen exchange in tunnel junctions based on NdNiO3, a strongly ...
Long-range, spin polarized Josephson supercurrents across a half-metal
The Josephson effect results from the coupling of two superconductors through a non-superconducting material (insulator, ordinary metal, graphene...), allowing the passage of an electric supercurrent ...
Large topological Hall effect in SrIrO3 induced by proximity with a half-metallic ferromagnet
The anomalous Hall effect (AHE) is an intriguing transport phenomenon occurring typically in ferromagnets as a consequence of broken time reversal symmetry and spin-orbit interaction. ...
