Abstract
The influence of grain size on the breadth of the superconducting transition in polycrystalline tin has been studied. The transition has been detected using an a-c. induction method. A range of grain sizes from 0.2 mm to 10 mm was used and the corresponding range in transition breadth is from 75 to 18 millidegrees. The influence of the grain boundaries is to broaden all the transition curves towards higher temperatures from a well-defined end point which is common to all the curves.
