Magnetoreflectance and magnetization of the semimagnetic semiconductor Zn 1 - x Fe x Se

Magnetoreflectance and magnetization of the semimagnetic semiconductor Zn 1 - x Fe x Se Magnetoreflectance measurements of excitonic interband transitions are used to study the exchange interaction between band electrons and localized Fe d electrons in cubic Zn 1 - x Fe x Se ( x <0.06) at T =1.9 K and B <5 T. Combining exciton splitting with the magnetization of the same samples, we determined the conduction- and valence-band exchange constants N 0 α=0.25 eV and N 0 β=-1.76 eV. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review B American Physical Society (APS)

Abstract

Magnetoreflectance measurements of excitonic interband transitions are used to study the exchange interaction between band electrons and localized Fe d electrons in cubic Zn 1 - x Fe x Se ( x <0.06) at T =1.9 K and B <5 T. Combining exciton splitting with the magnetization of the same samples, we determined the conduction- and valence-band exchange constants N 0 α=0.25 eV and N 0 β=-1.76 eV.
