Necessary conditions for spin-resolved Josephson diode effect across strongly spin-polarized magnetic materials

Danilo Nikolić, Danilo Nikolić, Niklas L. Schulz +1

We present a set of necessary conditions for the appearance of charge and spin Josephson diode effects across strongly spin-polarized inhomogeneous magnetic materials (FM) placed b…

Purely even harmonic Josephson current due to crossed pair transmission across strongly spin-polarized materials

Niklas L. Schulz, Danilo Nikolić, Danilo Nikolić +1

We revisit the problem of the second harmonic generation in the current-phase relation across ferromagnetic bilayers placed between BCS superconductors. In particular, we consider…

Theory of quantum-geometric charge and spin Josephson diode effects in strongly spin-polarized hybrid structures with noncoplanar spin textures

Niklas L. Schulz, Danilo Nikolić, Matthias Eschrig

We present a systematic study of the spin-resolved Josephson diode effect (JDE) in strongly spin-polarized ferromagnets (sFM) coupled to singlet superconductors (SC) via ferromagne…

Quantum-geometric spin and charge Josephson diode effects

Niklas L. Schulz, Danilo Nikolić, Matthias Eschrig

We present a general mechanism for large charge and spin Josephson diode effects in strongly spin-polarized superconductor-ferromagnet hybrid structures with a noncoplanar spin tex…

Spin-resolved Josephson diode effect through strongly spin-polarized conical magnets

Danilo Nikolić, Danilo Nikolić, Niklas L. Schulz +2

We present a theoretical study of the spin-resolved Josephson diode effect in junctions comprising strongly spin-polarized conical magnets (FM) coupled to singlet superconductors (…
