MO images of the self field of YBCO on RABiTS. A laser scribed link can be seen in the images with dimensions of ~0.5 x 1 mm.

a) MO image of the link at I = 0.5 Ic, well before the onset of dissipation.

b) I = Ic, and

c) I = 1.5 Ic, a highly dissipative state. The transition from a) to c) with increasing applied current is extremely gradual.

Yet another laser scribed link in a YBCO on RABiTS sample. The link is ~300 µm wide. Images are shown for an increasing applied currents. Ic = 560 mA. The only difference between e) and f) is a rotation of the polarizer in the MO microscope, demonstrating that the colors are relative.

MO image of YBCO on a deformation textured substrate. A laser scribed link can be seen in the images with dimensions of ~0.4 x 1.1 mm. This image is an image of the self field of the link at an applied current of 2.4 A, equal to Ic.
