摘要

We present results on ultra low noise YBa_2Cu_3O_(7-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 T_C. The white flux noise below 1μΦ_0/Hz~(1/2) at T = 8K makes our nanoSQUIDs very attractive for the detection of small spin systems.
