Title: Anisotropy in MgB2
Author: Lima, O. F. de
Cardoso, C. A.
Abstract: The first direct measurement of an anisotropic superconducting property in MgB2 was achieved for the bulk nucleation field Hc2, in a sample of aligned crystallites. It was found a ratio gamma(T) = Hab c2/ Hc c2= 1.6 - 1.9, for T varying from 32 K to 26K, between H applied parallel to the ab plane, and along the c direction. The anisotropy of the induced critical current density was evaluated through the Bean model to be ab c/ Jc c~ 1.5. We present here a brief review of these studies in connection with current results found in the literature.
