Journal ArticleDOI
High cooperativity in coupled microwave resonator ferrimagnetic insulator hybrids.
Hans Huebl,Christoph W. Zollitsch,Johannes Lotze,Fredrik Hocke,Moritz Greifenstein,Achim Marx,Rudolf Gross,Sebastian T. B. Goennenwein +7 more
TL;DR: The observation of strong coupling between the exchange-coupled spins in a gallium-doped yttrium iron garnet and a superconducting coplanar microwave resonator made from Nb demonstrates that exchange-Coupled systems are suitable for cavity quantum electrodynamics experiments, while allowing high integration densities due to their spin densities of the order of one Bohr magneton per atom.

TL;DR: In this paper, a tunable coupling between two superconducting transmission line resonators is realized by a non-hysteretic rf SQUID acting as a flux-tunable mutual inductance between the resonators.
Journal ArticleDOI
Tunable magnon-magnon coupling in synthetic antiferromagnets
A. Sud,Christoph W. Zollitsch,Akira Kamimaki,Troy Dion,Safe Khan,Satoshi Iihama,Shigemi Mizukami,Hidekazu Kurebayashi +7 more
TL;DR: In this article, the coupling strength is controlled by the out-of-plane tilt angle as well as the interlayer exchange field in synthetic antiferromagnets (SyAFs) using microwave spectroscopy at room temperature.
