Abstract
Our sample is prepared by evaporating a type-I superconductor Pb on a capillary plate with 1-μm-diameter hole and 1.8-μm pitch. We measure the magnetization curve of sample by means of a superconducting quantum interference device magnetometer in the accurate low fields on the order of mG. We find a clear matching magnetization peak at −8.13 G near T c. We find that T c oscillates as a function of field with a period of Φ 0. The whole superconductive HT phase diagram is determined by measuring the magnetization curve. The spontaneous magnetization appears as a function of decreasing temperature even at 0 G. This might be due to the attractive interaction between vortices.
