“…This study on the light rare-earth substitution for Ba in Eu123 has shown that Pr behaves almost like other rare-earth elements when it is substituted for Ba in Eu123. The results of the polycrystalline compound Eu(Ba 1:3 R 0:7 )-Cu 3 O 7À 17) investigated by Pr Mossbauer spectroscopy explain why Pr behaves very similarly to other þ3 cations (La, Nd) when substituted for Ba in this system.…”

“…3 On the other hand a large number of results obtained with different techniques point to a 3 + valence state of Pr (see, e.g., Refs. [12][13][14]. Thus, Pr is the exceptional three-valent rareearth element which substantially influences the superconducting and magnetic properties of R 1−x Pr x Ba 2 Cu 3 O 7−δ .…”

“…Many experiments have been carried out for Pr@Ba on samples of Pr123 [6, 9 -12], Y123 [13,14], Sm123 [12], Eu123 [15,16], Gd123 [17], and other rare earth elements R@Ba such as La and Eu@Ba in Pr123 [18], La@Ba in Y123 [14], or in Pr123 [4], Nd@Ba in Nd123 [13,19], Ho,Y and Ca@Pr in Pr123 [20], Ba@Pr in Pr123 [21,22]. Through these experiments different structural and valence modifications related to Pr are reported.…”
