Query: Micro-SQUID characteristics   We report on the dependence on field and temperature of the critical current
of micro-SQUIDs: SQUIDs with diameters as small as 1 micron, using Dayem
bridges as weak links. We model these SQUIDs by solving the Ginzburg-Landau
equations with appropriate boundary conditions to obtain the supercurrent-phase
relationships. These solutions show that the phase drops and depression of the
order parameter produced by supercurrent flow are often distributed throughout
the micro-SQUID structure, rather than being localized in the bridge area, for
typical micro-SQUID geometries and coherence lengths. The resultant highly
non-sinusoidal current-phase relationships $I_c(\phi)$ lead to reduced
modulation depths and triangular dependences of the micro-SQUID critical
currents on applied magnetic flux $I_c(\Phi)$. Our modelling agrees well with
our measurements on both Al and Nb micro-SQUIDs.
