|Title:||Charge Ordering In The Electron Doped Ca1-xyxmno3 Manganites|
|Abstract:||Structural studies on the electron doped Ca1-xYxMnO3 are presented. At 300 K, orthorhombic O-phase was observed in all cases, associated to low electric resistivity and high Curie-Weiss temperature. For samples with x > 0.07, structural phase transitions to more distorted orthorhombic and monoclinic phases were found at T < 170 K. In these phases only weak ferromagnetic interactions were observed. © 2002 Elsevier Science B.V. All rights reserved.|
