 note = {A reactive sputtering equipment was designed and constructed to make a superconducting
thin film with high superconducting transition temperature Tc. Using this, NbN film with Tc-15K which is Known to be the highest for this material was obtained.
In order to cooling down these samples, "Cryomech" refrigerator was used for the first time.
It became clear that this refrigerator is quite suitable for the study of materials with high Tc.},
