Peierls Transition

We investigate theoretically manganese oxides where the colossal magnetoresistance (CMR) is observed. We obtain the Curie temperature Tc using a Kondo lattice model for paramagetic to ferromagnetic transition. We also acquire the charge-ordered transition temperature TCO applying spin-Peierls transition. We calculate the isotope exponents of Mn ion and O ion such as αc for Tc and αCO for TCO. Calculated αc of O ion is less than 0.9 and αCO is ~-(0.1~0.9).
