Magnetic X-ray diffraction on Tb0.5Dy0.5Cu2

摘要

We present a magnetic X-ray diffraction study on Tb0.5Dy0.5Cu2. The Dy and Tb L-3 resonances were used to separate the magnetic signal of the two species. They differ in the variation of the magnetic propagation vector and intensity as a function of temperature. Finally, they exhibit different lock-in temperatures to the commensurate low-temperature magnetic phase. For the interpretation, a non-collinear magnetic moment configuration and the formation of magnetic clusters will be considered. (C) 2003 Elsevier B.V. All rights reserved. [References: 7]
