There is a weak magnetic-field dependence which has been neglected. It produces a < 1% error for our largest applied field.

    • Essentially the same expression can be obtained more generally in London theory simply by equating the kinetic-energy density to the condensation energy. This Jd(0,0) is 1.84 times larger.

    • We found that the temperature rise did not depend on whether the sample was in a vacuum or surrounded by helium vapor. Presumably the short time scales make convection ineffective. For this reason it also seems likely that direct contact with a liquid cryogen will not reduce heating significantly.

    • Rbd is somewhat sample dependent because of its sensitivity to interface roughness.

    • To the best of our knowledge, the specific heat of LaAlO3 has not been published. The value taken is typical of other perovskite compounds such as SrTiO3 and YBa2- Cu sub 3 O sub { 7 - δ }_;

    • In principle, the H=0 curves in Fig. 2(a) are at different self-fields (app 10 G at the highest J = 106 A/cm2). However, the resulting transition broadening was calculated to be negligible compared with the pair-breaking effect.

    • There is one exception [, ] where the authors report Jc= 1.3 times 109 A/cm2. However, close inspection of the information given implies an electric-field criterion 3–4 orders of magnitude greater than the accepted standard of 1 muV/cm.
