Description

The first measurement of both the size and shape of the region of the Fermi surface of yttrium known as the open-quotes webbingclose quotes is reported. This particular Fermi surface feature is of considerable interest because it is very similar to that found in a number of the heavier rare earth metals, where it is believed to play a vital role in driving the exotic magnetic structures found therein. In this positron study, two-dimensional angular correlation measurements combined with three-dimensional reconstruction provide a direct image of this part of the yttrium Fermi surface. copyright 1997 The American Physical Society
