Possible Interaction: Copper and Gadolinium

“Other metals such as iron, copper , and calcium can interfere with the binding between gadolinium and its carrier because they compete for the same binding site.”

“The quasi-systematic ferromagnetic nature of the coupling between Cu and Gd has been corroborated by a considerable amount of experimental data, and a recent report has established the theoretical grounds of this observation.”

“Substitution of Cu by Ni or Zn not only depresses superconductivity but also reduces the antiferromagnetic ordering temperature {ital T}{sub {ital N}} of Gd ions, suggesting an interaction between Gd ions and the Cu-O plane.”

“The strong bonds formed between copper and gadolinium provide a thermochemical driving force for copper gadolinium-alloy formation.”

“Fluctuations in the 4f moment associated with the gadolinium contribute strongly to the copper relaxation rate, and this contribution will depend strongly on the This separation differs considerably for the two copper sites.”
