Abstract
IN a recent paper1 I discussed the transition of a metal in an external magnetic field to the supra-conductive state on the usual thermodynamical methods. The chief results of that paper may be summarised as follows: (1) Simple phenomena and sharp transitions can only be expected if we have to do with a long-shaped or very flat body, orientated parallel to the field. (2) The experimental data permit us to consider only the transitions between the normal state and those supraconductive states where the induction B equals 0 (B has been called G). (3) A relation has been derived in analogy to Clapeyron's equation, which was verified for tin2 in low external fields (Rutger's equation). (4) From the validity of Rutger's equation the conclusion may be drawn that, within the limits of accuracy, dQ/T = dS, is true for the transition. (5) If the body has not the shape of a very oblong or very flat body parallel to the field, supra-con-ductivity will vanish gradually3, when the field or the temperature is raised. Supraconductivity will then be disturbed in some parts of the body, while it can persist in other parts, the persisting parts being long-shaped or very flat regions (needles or razor blades) parallel to the field.
