Abstract SrIrO3 is a correlated semimetal with narrow t2g d-bands of strong mixed orbital character resulting from the interplay of the spin-orbit interaction due to heavy iridium atoms and the band folding induced by the lattice structure. In ultrat

Memristors based on oxide tunnel junctions are promising candidates for energy efficient neuromorphic computing. However, the low power sensing of the nonvolatile resistive state is an important challenge. We report the optically induced sensing of t

De Luca, Roberto Di Capua, Emiliano Di Gennaro, Giacomo Ghiringhelli, Cinthia Piamonteze, Daniele Preziosi, Benoit Jouault, Mariona Cabero, José María González-Calbet, Carlos León, Jacobo Santamaria, Alessia Sambri, Daniela Stornaiuolo, Marco Salluzzo

Interfacial inversion symmetry breaking gives rise to electronic properties that differ substantially from those of the bulk constituent materials. Here, we report on the realization of an artificial ferromagnetic quasi-two-dimensional electron gas (

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. It can be caused by two microscopically distinct mechanisms, namel
