Addendum to $lqlq Doping-Dependent Magnetic Structure of Tb$_{1-x}$$Ca$$_{x}$$MnO$$_{3}$$ rqrq

Machida, Akihiko; Moritomo, Yutaka*; Oyama, Kenji*

In order to investigate interrelation between the lattice structure and the magnetic structure, we have performed Rietveld structural analysis on the neutron powder patterns for Tb$$_{1-x}$$Ca$$_{x}$$MnO$$_3$$ at low temperature. In the concentration range of $$0.65 leq x leq 0.85$$, we observed the Bragg reflections due to the CE-like- and C-type structures. In this range, the powder patterns were reproduce by the two-phase model with $$Pnma$$ and $$P2_{1}/m$$ symmetries. The fractions of these phases change against concentration $$x$$. This variation of the fraction for the $$Pnma$$ phase is similar to the variation of the integrated intensities of the CE-like-type magnetic Bragg reflections. This indicates that the $$Pnma$$ phase is responsible for the CE-like spin-ordering. Furthermore, we discussed interrelation between the detailed lattice structure and magnetic structure.
