Los sistemas spin glass (SG) han sido objeto de múltiples investigaciones durante más de cuatro décadas, conocidos como sistemas de comportamiento complejo, consecuencia del carácter aleatorio en la disposición de sus espines; este comportamiento inicialmente investigado en sistemas binarios ha sido identificado en más de 500 sistemas. Experimentalmente a partir de mediciones de susceptibilidad magnética y resistividad eléctrica ha sido posible identificar este comportamiento, aunque con el tiempo han sido incluidas otras técnicas de caracterización. Se presenta un breve recorrido por lo que ha sido el desarrollo de la investigación en los SG que lejos de proporcionar información técnica o detallada del mismo, busca darle al lector una vista general de lo que ha sido la investigación en SG a nivel experimental hasta ahora.
Palabras Clave:
Spin glass systems (SG) have been the subject of multiple investigations for more than four decades, known as complex systems behavior, due to the randomness in the arrangement of their spins, this behavior initially investigated in binary systems has been identified in more than 500 systems. Experimentally from measurements of magnetic susceptibility and electrical resistivity has been possible to identify this behavior, but over time have been included other characterization techniques. We present a brief overview of what has been the development of research in the SG that far from providing technical or detailed information, it seeks to give the reader an overview of what research has been SG experimentally so far.
