Year: 2014

Type: article

Abstract: We present results on ultra low noise YBa2Cu3O7–δ (YBCO) nano Superconducting QUantum Interference Devices (nanoSQUIDs). To realize such devices, we implemented high quality YBCO nanowires, working as weak links between two electrodes. We observe critical current modulation as a function of an externally applied magnetic field in the full temperature range below the transition temperature TC. The white flux noise below 1μΦ0/Hz at T=8 K makes our nanoSQUIDs very attractive for the detection of small spin systems.
