Magnetic phase diagram for a non-extensive system: Experimental connection with manganites
M. S. Reis, J. P. Araujo, V. S. Amaral +1
In the present paper we make a thorough analysis of a classical spin system, within the framework of Tsallis nonextensive statistics. From the analysis of the generalized Gibbs fre…
