Spin-waves in a complex magnetic system: nonextensive approach
D. O. Soares-Pinto, M. S. Reis, R. S. Sarthour +1
In this paper we analyze the spin-wave excitations (magnons) of an inhomogeneous spin system within the Boltzmann-Gibbs framework and then connect the results with the nonextensive…
Physical meaning and measurement of the entropic parameter in an inhomogeneous magnetic systems
M. S. Reis, V. S. Amaral, R. S. Sarthour +1
In this paper we present a thorough analysis of two systems magnetically inhomogeneous: the manganite LaSrMnO/MgO and the amorphous alloy CuCo. In…
Experimental determination of the non-extensive entropic parameter
M. S. Reis, V. S. Amaral, R. S. Sarthour +1
We show how to extract the parameter from experimental data, considering an inhomogeneous magnetic system composed by many Maxwell-Boltzmann homogeneous parts, which after inte…
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…
