摘要
Eu0.65Sr0.35FexMn1-xO3 (x=0.1, 0.3 and 0.5) has been prepared using a standard solid state reaction method. The under-investigation compounds is found to crystallize in a single-phase orthorhombic structure in the P-bnm space group (62). The adiabatic polaron electronic transfer was obtained for all samples and the activation energy of x=0.1 sample is equal to 1.013 meV and slightly increase at x=0.3 (1.289 meV) while is doubled for x=0.5 to be 2.1065 meV. The magnetization-temperature dependence measurements of Eu0.65Sr0.35FexMn1-xO3 show the ferromagnetic ordering at low iron concentration x=0.1 and when iron concentration increase to x=0.5 the noncollinear magnetic ordering (the canted antiferromagnetic) is obtained. The magnetic phase transition (paramagnetic-ferromagnetic transition) in the Eu0.65Sr0.35Fe0.1Mn0.9O3 is observed at T-C of 150 K. For Eu0.65Sr0.35Fe0.5Mn0.5O3 the multi-magnetic phase transition is observed at T-C of 200K and T-N of 430 K. The resistivity at low temperature is measured. Theoretical Calculations using Monte Carlo code have been done. The magnetization as function of temperature has been calculated using Monte Carlo simulations for Eu0.65Sr0.35FexMn1-xO3 (x=0.0, 0.1, 0,2, 0.3, 0.4 and 0.5). Ising model is a suitable model to study the magnetization for our compounds. The internal energy for x=0 is the highest value compared with the other x values which have nearly a ground state value equal to 2.7 J (C) 2016 Elsevier B.V. All rights reserved.
