Instabilities and Insulator-Metal transitions in Half-Doped Manganites induced by Magnetic-Field and Doping
O. Cepas, H. R. Krishnamurthy, T. V. Ramakrishnan
We discuss the phase diagram of the two-orbital model of half-doped manganites by calculating self-consistently the Jahn-Teller (JT) distortion patterns, charge, orbital and magnet…

Doping and Field-Induced Insulator-Metal Transitions in Half-Doped Manganites
O. Cepas, H. R. Krishnamurthy, T. V. Ramakrishnan
We argue that many properties of the half-doped manganites may be understood in terms of a new two-(eg electron)-fluid description, which is energetically favorable at intermediate…
