Spin Polarons in the t - J Model
Any theory of high temperature superconductors must consider charge carriers (usually holes) moving through spins with short range antiferromagnetic order. (this is demonstrated, particularly, by the results of neutron (Birgeneau et al. 1988a, 1988b) and Raman (Lyons et al. 1988) scattering experiments. The two schools of thought on magnetic mechanisms for superconductivity focus either on the short-range an- tiferromagnetism or the long-range paramagnetism as the underlying cause of the phenomenon. It is not clear that these points of view are really distinct.
