Organic spintronics has grown up to be a popular field in recent years.It is known that one of the characteristic propertis of organic materials is that the carriers are nonlinear excitations,such as polarons and bipolarons,which bring novel effects in luminescence and conduction different from the inorganic counterparts.As a combination of ferromagnets and organic materials,organic ferromagnets look particularly attractive in the field.Recent progress in molecular electronics offers the prospect of designing spintronics devices based on organic ferromagnets,such as spin filters,spin diodes and spin valves [1-3].However,the first step is to understand the property of carriers in such materials,which has not been involved to now.In this work,we theoretically investigated the formation of polarons in organic ferromagnets with spin radicals [4].The results reveal a quite different picture of the polaron from that in normal organic materials,that is,spin-charge disparity.The charge distribution of the polaron is highly asymmetric under spatial reflection,due to spin radicals.On the contrary,the spin density is nearly symmetric.These results are discussed on the basis of real-space mean-field calculations and symmetry argument.This fundamental work displays the picture of polarons in organic ferromagnets,which will deepen the understanding of organic ferromagnets and trigger more interest in the further transport research.
