Coherent subgap transport in spin-split Josephson junctions
David Caldevilla-Asenjo, Gorm Ole Steffensen, Sara Catalano +6
We report the first experimental observation of subgap transport in ferromagnetic insulator/superconductor/insulator/superconductor junctions realized in EuS/Al/AlOx/Al vertical st…
Signatures of polarized chiral spin disproportionation in rare earth nickelates
Jiarui Li, Robert J. Green, Claribel Domínguez +12
In rare earth nickelates (RENiO), electron-lattice coupling drives a concurrent metal-to-insulator and bond disproportionation phase transition whose microscopic origin has lon…
Spin Hall magnetoresistance effect from a disordered interface
Sara Catalano, Juan M. Gomez-Perez, M. Xochitl Aguilar-Pujol +4
The Spin Hall magnetoresistance (SMR) emerged as a reference tool to investigate the magnetic properties of materials with an all-electrical set-up. Its sensitivity to the magnetiz…
Microcavity phonon polaritons from weak to ultrastrong phonon-photon coupling
Maria Barra-Burillo, Unai Muniain, Sara Catalano +6
Strong coupling between molecular vibrations and microcavity modes has been demonstrated to modify physical and chemical properties of the molecular material. Here, we study the mu…
Optical properties of LaNiO3 films tuned from compressive to tensile strain

The realization of both p-type and n-type operations in a single organic field effect transistor (OFET) is critical for simplifying the design of complex organic circuits. Typicall…
Room-temperature operation of a molecular spin photovoltaic device on a transparent substrate
Kaushik Bairagi, David Garcia Romero, Francesco Calavalle +5
Incorporating multifunctionality along with the spin-related phenomenon in a single device is of great interest for the development of next generation spintronic devices. One of th…
Length-scales of interfacial coupling between metal-insulator phases in oxides
