摘要：

The measurements of thermal expansion alpha(T) of MgB2, were carried out at low temperatures both in zero magnetic field H and at H = 36 kOe. The anomalous (negative) thermal expansion and strong magnetic field influence on the alpha(T) was observed. The results indicate the similarity of the anomalous properties of MgB2, and oxide high temperature superconducting systems. (C) 2002 Elsevier Science B.V. All rights reserved.
