Double exchange model for RuSr_2(Eu,Gd)Cu_2O_8
H. Aliaga, A. A. Aligia
We propose a double exchange model to describe the RuO_2 planes of RuSr_2(Eu,Gd)Cu_2O_8. The Ru^+5 ions are described by localized spins, and additional electrons provided by the s…
Magnetic polarons in Ca_(1-x)Y_xMnO_3
H. Aliaga, M. T. Causa, M. Tovar +1
Experimental evidence show that in the magnetoresistive manganite Ca_(1-x) Y_xMnO_3, ferromagnetic (FM) polarons arises in an antiferromagnetic (AF) background, as a result of the…
Double Exchange in Electron Doped Ca1-xYxMnO3 Manganites
H. Aliaga, M. T. Causa, A. Butera +6
We have studied structural, magnetic and transport properties as a function of temperature and magnetic field in the electron doped manganite YxCa1-xMnO3, for 0<x<0.25. We found th…
Phase diagram for Ca_{1-x}Y_xMnO_3 type crystals
H. Aliaga, R. Allub, B. Alascio
We present a simple model to study the electron doped manganese perovskites. The model considers the competition between double exchange mechanism for itinerant electrons and antif…
