Negative thermal expansion of HTSC-type structures: low temperature structure measurements on Eu₁₊x(Ba₁₋yRy) ₂₋xCu₃O₇₋d compounds and theoretical treatment

Анотація:

The temperature dependences of the lattice parameters were investigated on the perovskite-like structures Eu₁₊x(Ba₁₋yRy) ₂₋xCu₃O₇₋d with Ba substitution by light rare earth, using x-ray diffraction techniques. A negative thermal expansion effect was observed and explained in detail.
