Temperature evolution of the effective magnetic anisotropy in the MnCrO spinel
Dina Tobia, Julián Milano, María Teresa Causa +1
In this work we present a study of the low temperature magnetic phases of polycrystalline MnCrO spinel through dc magnetization and ferromagnetic resonance spectroscopy (FM…
R-M interactions in R2BaMO5 (R=Y or Gd and M=Cu or Zn)
G. F. Goya, R. C. Mercader, L. B. Steren +3
R2BaMO5 (R = Gd, Y and M = Cu, Zn) oxides have been studied by specific heat, dc magnetic susceptibility, and electron paramagnetic resonance (EPR). For one member of the series wi…
Charge disproportionation in YNiO : ESR and susceptibility study
M. T. Causa, R. D. Sánchez, M. Tovar +2
We present a study of the magnetic properties of YNiO in the paramagnetic range, above and below the metal-insulator (MI) transition. The dc susceptibility, (measure…
High temperature susceptibility in electron doped Ca1-xYxMnO3: Double Exchange vs Superexchange
H. Aliaga, M. T. Causa, M. Tovar +6
We present a study of the magnetic properties of the electron doped manganites Ca1-xYxMnO3 (for 0<=x<=0.25) in the paramagnetic regime. For the less doped samples (x<=0.1) the magn…
Evidence of strong antiferromagnetic coupling between localized and itinerant electrons in ferromagnetic Sr2FeMoO6
M. Tovar, M. T. Causa, A. Butera +4
Magnetic dc susceptibility () and electron spin resonance (ESR) measurements in the paramagnetic regime, are presented. We found a Curie-Weiss (CW) behavior for (T) with a fe…
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…
