Abstract
Se estudia un modelo tipo Ising tomando en cuenta las interacciones de corto y
largo alcance, así mismo como el posible efecto de la superficie del sistema y
la forma del mismo sobre las propiedades magnéticas del material. Esto se
realiza para investigar el comportamiento de los sistemas compuestos por
nanopartículas ordenadas en una matriz. Ademas se analiza el papel que juega
la relación entre numero de partículas en la superficie con las que se
encuentran en el volumen de la matriz con respecto al comportamiento de
histeresis del sistema.
An Ising model is studied, taking into account short and long range interactions, as well as the possible effect of the system surface and its shape on the magnetic properties of the material. This is done to investigate the behavior of systems composed of nanoparticles ordered in a matrix. In addition, the role of the relationship between the number of particles on the surface and those in the volume of the matrix with respect to the behavior of system hysteresis is analyzed.
