The same physics that correctly predicted superconductivity of PrBa{sub 2}Cu{sub 3}O{sub 7} also explains flux pinning by Ba-site magnetic rare-earth ions in (rare-earth){sub 1+u}Ba{sub 2{minus}u}Cu{sub 3}O{sub x} compounds with x{approx}7. The customary cuprate-plane picture of superconductivity must be revised in the same way to consistently explain the observations either of flux pinning or of PrBa{sub 2}Cu{sub 3}O{sub 7} superconductivity with T{sub c}{approx}90 K. {copyright} {ital 1997 American Institute of Physics.}
