High-field magnetisation of RCo9Si2 compounds
- 1. Van der Waals-Zeeman Laboratory, University of Amsterdam, Valckenierstraat 65, NL-1018 XE Amsterdam (Netherlands)
Description
We prepared RCo9Si2 compounds in polycrystalline form with R representing Sm, Gd, and Tb. The magnetisation in fields up to 35 T was studied at 4.2 K on powder particles free to orient in the applied magnetic field. The Sm compound is ferromagnetic, the Gd and Tb compounds were found to order ferrimagnetically. The moments on the Co-sublattice are found to be about 0.9μB/Co-atom. For the ferrimagnetic samples, the exchange-coupling constant JRT/k can be estimated from the slope of the high-field magnetic isotherm. This coupling constant is found to be 6.8 K for both the Gd and the Tb compound. To achieve a proper description of the magnetisation of TbCo9Si2 a three-sublattice model is used. (orig.)
