It is shown that a wide class of physical processes named low-temperature creep (or Robin Hood systems) has to demonstrate self-organized criticality. At least "real" and "toy" models (1D and 2D) demonstrate long range (restricted by the model size only) spatial correlation in Monte Carlo simulation. The models can be used for investigation of such phenomena as dislocation glide, movement of flux in superconductors, movement of domain walls in magnetics, grain boundaries in polycrystals, plastic deformation and so on.
