English title:	CRITICAL TEMPERATURE AND HYSTERESIS LOOPS OF AN ISING-TYPE FERROMAGNETIC SYSTEM OF SPINS 1 AND 2: A MONTE CARLO STUDY
Spanish title:	TEMPERATURA CR�TICA Y LAZOS DE HIST�RESIS DE UN SISTEMA FERROMAGN�TICO TIPO ISING DE ESPINES 1 Y 2: UN ESTUDIO MONTE CARLO
English abstract:	In the present work, the thermomagnetic properties of a ferromagnetic system of integer magnetic moments S = �2, �1, 0 and Q = �1, 0 were analyzed by means of Monte Carlo simulation techniques and a thermal bath algorithm. The ferromagnet was configured through a two-dimensional square lattice, considering nearest-neighbors exchange couplings between S and Q spins (Si → Qj), next-nearest-neighbors exchange couplings between S-type spins (Si → Sj), and interactions with an external magnetic field h. The effects of the next-nearest-neighbor exchange parameter (J2) and a magnetic field h on the phase diagrams at finite temperature of the magnetizations, the magnetic susceptibility, and the critical temperature were analyzed, as well as the hysteresis behavior for different temperature values. The critical temperature (TC) is proportional to \|h\| and \|J2\|.
Spanish abstract:	En el presente trabajo se analizaron, mediante t�cnicas de simulaci�n Monte Carlo y un algoritmo tipo ba�o t�rmico, las propiedades termomagn�ticas de un sistema ferromagn�tico de momentos magn�ticos enteros S = �2, �1, 0 y Q = �1, 0. El ferromagneto se configur� a trav�s de una red bidimensional cuadrada, considerando acoplamientos de intercambio a primeros vecinos S y Q (Si → Qj), a segundos vecinos tipo S (Si → Sj) e interacciones con un campo magn�tico externo h. Se analizaron los efectos del par�metro de intercambio a segundos vecinos (J2) y un campo magn�tico h sobre los diagramas de fase a temperatura finita de las magnetizaciones, la susceptibilidad magn�tica y la temperatura cr�tica; as� como tambi�n el comportamiento de hist�resis para diversos valores de temperatura. La temperatura cr�tica (TC) es proporcional a \|h\| y \|J2\|.
