Abstract
Magnetization measurements were carried out on cylindrical samples of pure tin with diameters of 7, 10, and 122 μm and very clean and smooth surfaces in the temperature range from 3.62 to 3.72°K. The magnetization was found to be reversible and linear with the applied field H0<Hsh. Considerable superheating up to fields Hsh=2.25Hcb has been observed.
