Abstract
We measured the inductances of submicrometerwide strip lines by using DC superconducting quantum interference devices (SQUID's) fabricated from a single layer of YBa/sub 2/Cu/sub 3/O/sub 7/ thin film, The measured inductances coincided well with some numerically calculated inductances consisting of a magnetic and kinetic component. The proportion of the magnetic component in the total inductance for the line width of 2 /spl mu/m was estimated from calculation to be 56%, The kinetic component increased with the decrease of the line width and was dominant for line widths less than 1 /spl mu/m. The inductance per square at 4.2 K was measured to be 1.3 pH//spl square/ for line widths from 0.5 to 2 /spl mu/m.
