Inhaltszusammenfassung
We study the dc transport properties of (Ga,Mn)As diluted magnetic semiconductors with mn concentration varying from 1.5% to 8%. both diagonal and hall components of the conductivity tensor are strongly sensitive to the magnetic state of these semiconductors. transport data obtained at low temperatures are discussed theoretically within a model of band-hole quasiparticles with a finite spectral width due to elastic scattering from mn and compensating defects. the theoretical results are in go...We study the dc transport properties of (Ga,Mn)As diluted magnetic semiconductors with mn concentration varying from 1.5% to 8%. both diagonal and hall components of the conductivity tensor are strongly sensitive to the magnetic state of these semiconductors. transport data obtained at low temperatures are discussed theoretically within a model of band-hole quasiparticles with a finite spectral width due to elastic scattering from mn and compensating defects. the theoretical results are in good agreement with measured anomalous hall effect and anisotropic longitudinal magnetoresistance data.» weiterlesen» einklappen
