| Research Abstract |
We have found that nearly ferromagnetic itinerant electrons in TiCo, which is a 3d-band compound, become superconducting below approximately 50 mK. The normal state properties have been studied in detail, and reconfirmed to have characteristic of nearly ferromagnetic itinerant electron system. It has been found that the material includes a small number of ferromagnetic clusters and shows typical magnetic aftereffects. The size and quantity of the ferromagnetic clusters have been clarified to be related to the superconducting transition temperature. The heat capacity of LaPt3Si has also been studied with the similar interest.
