Spin systems

Spin systems are models used in physics and chemistry to describe the magnetic behavior of particles, like electrons, that possess an intrinsic property called "spin." Think of spin as a tiny magnetic arrow inside each particle that can point in different directions. In a spin system, these arrows interact with each other, aligning or opposing based on their surroundings, which influences the material's magnetic properties. Understanding these interactions helps scientists analyze phenomena such as magnetism, phase transitions, and quantum behavior in various materials.
