En. Solov'Eva et al., Effect of MgO and Al2O3 dopants on phase composition and electrical properties of YBa2Cu3O6.5+delta, RUS J AP CH, 72(10), 1999, pp. 1673-1676
The effect of MgO and Al2O3 addition on the phase composition and electrica
l properties of YBa2Cu3O6.5+delta was studied both in the case of partial s
ubstitution of yttrium by aluminum or barium by magnesium and for YBa2Cu3O6
.5+delta + MgO(Al2O3) compositions.
