The Diamond Superconducting Quantum Interference Device

Résumé

Diamond is an electrical insulator in its natural form. However, when doped with boron above a critical level (~0.25 at.%) it can be rendered superconducting at low temperatures with high critical fields. Here we present the realization of a micrometer scale superconducting quantum interference device $\mu$-SQUID made from nanocrystalline boron doped diamond (BDD) films. Our results demonstrate that $\mu$-SQUIDs made from superconducting diamond can be operated in magnetic fields as large as 4T independent on the field direction. This is a decisive step towards the detection of quantum motion in a diamond based nanomechanical oscillator.
