Tb-based silicate apatites showing slow magnetization relaxation with identical parameters for the Tb(3+) and Dy(3+) counter ions
Tb-diluted and Tb-rich apatite-type silicates with compositions Y(7.75)Tb(0.25)Ca(2)(SiO(4))(6)O(2) and Tb(8)Ca(2)(SiO(4))(6)O(2), respectively, exhibit field induced multiple slow relaxation of magnetization. The former reveals two slow relaxation paths, the latter only one with a longer relaxation...

description | Tb-diluted and Tb-rich apatite-type silicates with compositions Y(7.75)Tb(0.25)Ca(2)(SiO(4))(6)O(2) and Tb(8)Ca(2)(SiO(4))(6)O(2), respectively, exhibit field induced multiple slow relaxation of magnetization. The former reveals two slow relaxation paths, the latter only one with a longer relaxation time of several seconds. The relaxation features of the Tb-diluted one are comparable with those of analogue compounds, where Tb is replaced by Dy, as well as with those of a Tb-doped calcium phosphate apatite. The relaxation parameters of the Tb-rich compound virtually match those of the Dy-based analogue Dy(8)Ca(2)(SiO(4))(6)O(2). The latter represents the first instance of independence of magnetization relaxation on the nature of a paramagnetic rare-earth metal ion in single ion magnet like materials. |
