Damage spreading in a three-dimensional Ising model in a magnetic field
G. Le Caër
The time evolution of two ferromagnetic Ising cubic systems, which differ by the orientation of a single spin at t=0, has been studied in a magnetic field B by computer simulation. The critical field B c (T), above which the previous initial damage does not spread, has been determined. The magnetisation for B=B c is very well approximated by M(B c )=1-exp(-T c /T) in the range of T values investigated. The concentration of minority spins at B c (T) differs strongly from the corresponding concentration for percolation at T.
