Notes:
A new series of 1223-type (Tl,Cr)-based cuprates, (Tl,Cr)(Sr,Ba)2Ca2Cu3Oz, have been successfully synthesized and identified by powder x-ray diffraction and electron diffraction analyses. Ba partial substitution for Sr promotes the formation of (Tl,Cr)-based 1223-type compounds. Nominal samples, (Tl1−xCrx)-(Sr2−yBay) Ca2Cu3Oz, with 0.15≤x≤0.50 and 0.50≤y≤1.50 are pure or nearly pure 1223 phase and exhibit Tc(ρ=0) in the range of 104–114 K. This new (Tl,Cr)-based high-Tc material may be of importance in practical applications.
