摘要：

We performed dc-magnetization measurements in low magnetic fields (>250 Oe) on an untwinned single crystal of Y2Ba4Cu8O16 which exhibits a superconducting transition at 74 K. From isothermal magnetization curves we determined Hc1(T) and its anisotropy along the three crystallographic axes. We do not find any significant anisotropy between the a and b axes. © 1990.
