1 Jun 2006 | Subject: | Mesoscopic Systems and Quantum Hall Effect | Abstract: | We propose mechanical force realization based on flux quantization in the pico-Newton range. By controlling the number of flux quantum in a superconducting annulus, a force can be created as integer multiples of a constant step. For a 50 nm-thick Nb annulus with the inner and outer radii of 5 $mu$m and 10 $mu$m, respectively, and the field gradient of 10 T/m the force step is estimated to be 184 fN. The stability against thermal fluctuations is also addressed. | Source: | arXiv, cond-mat/0606022 | Services: | Forum | Review | PDF | Favorites |
