Abstract
Dilatometry is used to study the temperature dependence of the coefficient of linear expansion in the high-temperature semiconductor Bi 2 Sr 2 CaCu 2 O y in the range 60–300 K. At temperature close to T c ,125–140, and 200–400 K anomalies were observed in α(T). Temperature hysteresis was found in the quantity δl/l measured during heating and cooling.
