Abstract:

The site distribution of Fe-57 in a series of YBa2Cu4-xFexOdelta superconducting samples (x = 0.025, 0.05 and 0.075) was determined by Mossbauer spectroscopy. Resistance vs. temperature studies were also performed in order to determine the influence that increasing concentration of Fe has on T-c.
