Chu (1,2,3) ( Department of Physics, University of Houston, Houston TX, TCSUH, University of Houston, Houston TX, L | | Abstract: | Recent reports of the detecting of ferromagnetism and superconductivity in ruthenium-cuprates have aroused great interest. Unfortunately, whether the two antagonistic phenomena coexist in the same space in the compounds remains unresolved. By employing the magneto-optical-imaging technique, ferromagnetism and superconductivity were indeed directly observed to coexist in the same space in RuSr2(Gd0.7Ce0.3)2Cu2O10 within the experimental resolution of ~ 10 (mu)m. The observation sets a length scale limit for models proposed to account for the competition between ferromagnetism and superconductivity, especially d-wave superconductivity, in this interesting class of compounds. | | Source: | arXiv, cond-mat/0105510 | | Services: | Forum | Review | PDF | Favorites | |
