Abstract
The critical properties of the electron-doped manganite La0.6Sr0.4Mn0.9V0.1O3 were investigated based on the data of static magnetization in the vicinity of the ferromagnetic-paramagnetic phase transition. According to the modified Arrott plot, Kouvel-Fisher method, and critical isotherm analysis, we have determined the critical parameters (T-C, beta, gamma, and delta) in the two characteristic regions of low and high magnetic fields. The estimated critical exponents are close with a 3D Ising model. The reliability of the critical exponent values was confirmed by the Widom scaling relation and the universal scaling hypothesis. Using the field dependence of RCP and Delta S-M, it was possible to evaluate the critical exponents of the magnetic transitions. These values are in good agreement with those obtained from the critical exponents using modified Arrott plot.
