Enhanced levitation force of partial melted (Y,Er)Ba2Cu3O7-8 superconductors with formation of minor 211 phase / Ahmad Kamal Yahya, Suzi Ahmad and Imad Hamadneh

Y0.5 Er 0.5 Ba2 Cu307-8 superconductors with Er2 O3 addition were prepared by partial melting and the effects of excess Er2 03 addition on the magnetic levitation force (MLF) of the partial-melted samples have been investigated. A non-linear relationship was observed between the MLF measured at 77 K...
