Reply to "Comment on 'Tetragonal to monoclinic transition in the metallic antiferromagnet Pr0.5Sr0.5MnO3"

In response to the comment by Raveau et al. [Phys. Rev. B 62, 6820 (2000)] the high-resolution neutron diffraction data taken below 135 K on Pr0.5Sr0. 5MnO3 are examined. A detailed;comparison of the results using the P2(1)/n and Fmmm symmetries is presented. It is shown that the refined atomic posit ions using the Fmmm cell are almost identical to those reported by Llobet e t al. [Phys. Rev. B 60, R9889 (1999)]. The unique significant difference is a shift Delta x = 0.010(5) in the coordinate of the oxygen O1. It is concl uded that the detailed physical mechanism that causes the transition given by Llobet et al. remains unaltered in the 2a(p), x 2a(p) x 2a(p) descriptio n.
