Spin-Flip Induced Magnetoresistance in Positionally Disordered Organic Solids
Spin-Flip Induced Magnetoresistance in Positionally Disordered Organic Solids
A model for magnetoresistance in positionally disordered organic materials is presented and solved using percolation theory. The model describes the effects of spin dynamics on hopping transport by considering changes in the effective density of hopping sites, a key quantity determining the properties of percolative transport. Faster spin-flip transitions open …
