Scalable memory for cryogenic electronics is an unsolved issue, hindering the development of a full superconducting computing architecture – which would enable quantum computers to get rid of all those microwave cables.
Use of hybrid superconducting-magnetic structures as memory has been proposed, but most ferromagnets are metals that have fringe magnetic fields, causing problems when putting them into superconducting devices.
In this poster, we will describe our results on thin films and prototype structures made from the rare earth nitrides (RENs), materials with the uniquely tunable conductivities, magnetisations and angular momentum states that make them the base of a plausible and scalable superconducting-magnetic memory.
