In condensed matter physics, a spin glass is a magnetic state characterized by randomness, besides cooperative behavior in freezing of spins at a temperature called 'freezing temperature' Tf. In ferromagnetic solids, component atoms' magnetic spins all align in the same direction. Spin glass when contrasted … Visa mer It is the time dependence which distinguishes spin glasses from other magnetic systems. Above the spin glass transition temperature, Tc, the spin glass exhibits typical magnetic … Visa mer In this model, we have spins arranged on a $${\displaystyle d}$$-dimensional lattice with only nearest neighbor interactions similar to the Ising model. This model can be solved exactly for … Visa mer The infinite-range model is a generalization of the Sherrington–Kirkpatrick model where we not only consider two spin interactions but $${\displaystyle r}$$-spin interactions, where $${\displaystyle r\leq N}$$ and $${\displaystyle N}$$ is … Visa mer A detailed account of the history of spin glasses from the early 1960s to the late 1980s can be found in a series of popular articles by Philip W.
