Аннотация: The effect of the partial substitution of Cu for Al on the structural, compositional, and magnetic properties of polycrystalline compounds YBa2Cu3O7-δ was studied. All prepared samples turned out to be single-phase with a small fraction of Ba secondary phases. Substitution of more than 2% aluminum causes an increase in spurious phaПоказать полностьюses. DC susceptibility measurements show that the superconducting transition temperature T C decreases. Hysteresis loops show that magnetic irreversibility decreases with increasing Al content. The critical current density J C obtained using the Bean formula does not follow the same change. Al compensates for a decrease in J C and an increase in its content near the solubility limit gives a higher J C than in an undissolved sample. © Published under licence by IOP Publishing Ltd.
