摘要：

We have measured the magnetostriction L(H) of a single crystal of the heavy-fermion superconductor UBe13 using an all-silicon high-precision capacitance dilatometer. We find clear evidence for a transition to an antiferromagnetic state at TN 8.8 K, which is suppressed in a field by dTN/dH 0.36 K/T. At low temperatures we observe pronounced magnetostrictive oscillations, which we believe are de Haasvan Alphen oscillations due to an unusual aspect of the Fermi surface. © 1990 The American Physical Society.
