It is found that cold-rolling reduces the Curie temperature and raises the spin-freezing temperature remarkably. These results can be explained on the basis of the precipitation medal proposed by Borg and Violet.展开更多

We have measured its complex AC susceptibility as a function of temperature and found that below Tc there are two distinguishable superconducting 'phases'. In this note we report our experimental results.展开更多
