On-chip superconducting resonator devices for sensitive spin detection at high magnetic fields.

Abstract

The ability to probe spin-photon interactions using Electron Spin Resonance techniques has gained significant interest given the realization of hybridized states between microwave photons and different spin ensembles.1-3 On-chip superconducting resonators provides a way to inductively couple a spin two level system with a resonant electromagnetic mode leading to enhanced sensitivity4 when compared to traditional 3D resonators. We demonstrate the implementation of λ/4 resonator placed after a coplanar waveguide-to-stripline transition on a 20 nm thick Nb film. Temperature effects on the losses and resonance frequency are studied for bare and spin loaded resonators. A resonance signal at 0.62 T for a spin S=1/2 system is presented, demonstrating the feasibility of such on-chip structures for high magnetic field electron spin detection.
