Abstract

Structural feature of Eu_0.6Sr_0.4MnO₃ through the magnetic field induced insulator-to-metal transition has been investigated by using synchrotron X-ray diffraction in the magnetic field. While keeping the same Pnma symmetry, the lattice constant b jumps at the transition field, which is responsible for magnetoelastic effect. We suggest that the structural change through the transition is a rotation of MnO ₆ octahedron in a manner that the Mn-O-Mn angle increases toward 180°.
