Lattice Vibrational Modes in 1222 Phase of Pb-Sr-La-Ln-Cu-O System (Ln; Gd, Dy, Ho, Er)
Measurements of infrared absorption in insulating compounds of the 1222 phase of Pb-Sr-La-Ln-Cu-O system have been made. Lanthanoid (Ln) ions of Er, Ho, Dy and Gd have been used. Absorption peaks near 600 cm−1 an...

Infrared Absorption in Single Crystals of Bi-Sr-(Ca)-Cu-O System
Lattice absorption measurements in the spectral region between 750 cm−1 and 400 cm−1 have been made in single crystals of semiconducting Bi2Sr2CuO6 and superconducting Bi2Sr2CaCu2O8. The phenomenon known as the “...
