Abstract: Yttrium barium copper oxide (YBCO) junctions and direct current (dc) superconducting quantum interference devices (SQUIDs) based on 45 degree a-axis tilt grain boundaries were realized and fully characterized in terms of transport characteristics. The realized SQUIDs are among the first that employ such grain boundaries. High values of the I(sub C)R(sub N) quality factor and of the magnetic flux-to-voltage transfer parameter were derived.
