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…
