Abstract
WefabricatedGaAs-basedspin-LED(lightemittingdiode)structuresusinghalf-metallicFe3O4asspininjectorsandmeasuredthecircularpolarizationoftheelectroluminescence(EL).ThecircularpolarizationoftheELduetothespininjectionwasimprovedbythelowtemperaturegrowthoftheferromagneticlayer,comparedtotheroomtemperaturegrowth.Wealsostudiedtheexcitationwavelengthdependenceofthephotoluminescence(PL)spectraandthevariationoftheELspectrawithincreasingcurrent.TheexcesscarrierdependenceoftheELpeakswasfoundtobedifferentfromthatofthePLpeaks,whichwasexplainedbythecarrierinjectionintothebufferlayer.
