摘要：

The thermal expansion coefficient alpha(T) of MgB2 was measured at low temperatures both in a zero magnetic field and at H = 36 kOe. As in the oxide HTSCs, a region of anomalous (negative) thermal expansion and a strong effect of magnetic field on alpha(T) were revealed. The results obtained indicate the anomalous properties of MgB2 and the oxide HTSCs to follow a common pattern. (C) 2003 MAIK "Nauka/Interperiodica".
