Some recent developments in spin glasses

Magnetic state in RAgAl (R=Dy, Ho, Er)

“…In the recent years spin freezing has been very attractive from both the experimental and theoretical points of view [6][7][8]. Usually in a spin glass system magnetic atom disorder (MAD) occurs [9].…”

Spin Glasses

“…This feature is called frustration. Hamiltonian (1.2) possesses both quenched disorder and frustration, that become the distinctive features of a SG model [You05,Kaw10]. Anderson tried a mean field approach without, yet, averaging over the disorder.…”
