Abstract
The critical properties of the electron-doped manganite La0.7Sr0.25Na0.05Mn(1−x)TixO3 (x=0.0 and 0.1) were investigated based on the data of static magnetization measurements around Curie temperature TC. Various techniques such as modified Arrott plot, a Kouvel–Fisher method, and critical isotherm analysis were used to determine the values of the ferromagnetic transition temperature TC, as well as the critical exponents of β, γ and δ. The estimated results are close to those expected for three-dimensional Heisenberg class with short-range interaction. From the field dependence of RCP and ΔSM, it was possible to evaluate the critical exponents of the magnetic phase transitions. Their values are in good agreement with those obtained from the critical exponents using a modified Arrott plot (MAP).
