Lanthanide substitution by high pressure in the RuSr2GdCu2O8 magnetic superconductor

A systematic study of the structural and magnetic properties of the family RuSr2RECu2O8 (RE=Er, Ho, Y, Dy, Tb, Gd and Eu) has been performed. All these materials appear to be tetragonal (P4/mmm) and the unit cell volume decreases along with the lanthanide ion dimension. Differences are observed in t...

Zusammenfassung:A systematic study of the structural and magnetic properties of the family RuSr2RECu2O8 (RE=Er, Ho, Y, Dy, Tb, Gd and Eu) has been performed. All these materials appear to be tetragonal (P4/mmm) and the unit cell volume decreases along with the lanthanide ion dimension. Differences are observed in the magnetic behavior of these compounds. High pressure and high temperature are needed to synthesize most of the members of this family. 19 refs.
