Observation of 3D Heisenberg-like ferromagnetism in single crystal La_{0.875}Sr_{0.125}MnO_3

Abstract:

We report measurements and analysis of the magnetic critical phenomena in a single crystal of La${_{0.875}}$Sr${_{0.125}}$MnO${_3}$. The critical exponents associated with the ferromagnetic transition have been determined from ac susceptibility and dc magnetisation data. Techniques like the Kouvel$-$Fischer plots, modified Arrots Plots and the critical isotherm analysis were used for this purpose. The values of the the exponents $\gamma$, $\beta$ and $\delta$ obtained are found to match very ...
