Abstract—Single-crystal samples of the Bi2+xSr2–x–yCu1+yO6+
system revealed anomalous (negative)
thermal expansion in the temperature range 10–20 K. Magnetic fields of 1–3 T were found to strongly affect
the position and width of the anomaly region. A thermal-expansion singularity was detected at temperatures
T
30–50 K, which may be related to the formation of a pseudogap. © 2004 MAIK “Nauka/Interperiodica”.
