Fermi surface change with antiferro-quadrupolar ordering in DyB sub(2)C sub(2)

We have observed Fermi surface change with antiferro-quadrupolar (AFQ) ordering in DyB sub(2)C sub(2) via the de Haas-van Alphen effect. Some Fermi surfaces disappear in the AFQ state although they exist in the 'para' state. This observation cannot be explained by the change of the Brillou...

Summary:We have observed Fermi surface change with antiferro-quadrupolar (AFQ) ordering in DyB sub(2)C sub(2) via the de Haas-van Alphen effect. Some Fermi surfaces disappear in the AFQ state although they exist in the 'para' state. This observation cannot be explained by the change of the Brillouin zone due to the AFQ ordering. copyright 2001 Elsevier Science B.V. All rights reserved.
