The magnetic and superconducting properties of Pb[sub 2]Sr[sub 2](R/Ca)Cu[sub 3]O[sub 8], R=Pr, Ce, and Cm (abstract)
- Argonne National Laboratory, Argonne, Illinois 60439 (United States)
The series of compounds Pb[sub 2]Sr[sub 2](R/Ca)Cu[sub 3]O[sub 8], (R=Ce-Tm) are known to superconduct at temperatures as high as [ital T][sub [ital c]]=84 K. We have studied the relationship between superconductivity and magnetism in the Ce and Pr analogs. In addition, we report the synthetic route and the magnetic properties of the actinide analog Pb[sub 2]Sr[sub 2](Cm/Ca)Cu[sub 3]O[sub 8]. The parent compound Pb[sub 2]Sr[sub 2]CmCu[sub 3]O[sub 8] is not a superconductor, but shows evidence of long range magnetic ordering at about 18 K. This is a much higher temperature than is observed for any of the other R-ion parent compounds. These results will be discussed in terms of the different hybridization and bonding properties of the 4[ital f] and 5[ital f] electrons, and how these differences influence superconductivity. These results will be compared with the Pr and Cm analogs of the other superconducting series RBa[sub 2]Cu[sub 3]O[sub 7] and R[sub 2[minus][ital x]]Th[sub [ital x]]CuO[sub 4].
