  1. The critical current I C, the normal resistance (measured above gap) R N, the I C R N product, the width of the device w (in case of a SQUID twice the junction) and the distance between the electrodes L are reported. Devices JM10, JM5, SM4, SF8, and SD1 showed inverted magnetic patterns in the second cool down. The devices JM10 and JM5 are discussed in the text. The junctions start with a J in the device name, whereas the SQUIDs device names start with an S
