Lattice dynamical study of optical modes in Tl2Mn2O7 and In2Mn2O7 pyrochlores

Sonal Brown, H. C. Gupta, J. A. Alonso +1

The Raman, IR and force field have been investigated for A2Mn2O7 (A= Tl, In) by means of a short-range force constant model which includes four stretching and four bending force co…
