Abstract
Los hielos de espín son una serie de materiales magnéticos de dimensiones nanométricas que presentan una fascinante analogía con la estructura cristalina del hielo de agua, donde las reglas de coordinación de los momentos magnéticos en los vértices de la red imitan las reglas de orden del hielo. Estos sistemas presentan una frustración geométrica que impide el orden magnético de largo alcance, imposibilitando un estado de mínima energía y resultando en numerosas configuraciones altamente degeneradas y correlaciones de corto alcance. De manera adicional, los hielos de espín exhiben excitaciones no triviales en la forma de monopolos magnéticos emergentes, y han sido objeto de estudio durante los últimos años con el fin de diseñar materiales con propiedades magnéticas novedosas.
En resumen, los hielos de espín son un sistema intrigante que demuestra cómo los principios básicos y la geometría de la red pueden conducir a fenómenos complejos y propiedades exóticas en materiales magnéticos.
Spin ice systems are a kind of magnetic nanomaterials that exhibit a fascinating analogy with the crystalline structure of water ice, where the coordination rules of the magnetic moments at the lattice vertices mimic the ice rule. These systems present geometric frustration that prevents long-range magnetic order, making a minimal energy state impossible and resulting in numerous highly degenerate configurations and short-range correlations. Additionally, spin ice systems display non-trivial excitations in the form of emergent magnetic monopoles. In recent years, they have been studied to design materials with novel magnetic properties. To summarize, spin ice is an intriguing system that demonstrates how basic principles and lattice geometry can lead to complex phenomena and exotic properties in magnetic materials.
