IV_VI semimagnetic semiconductors: recent developments

摘要

Recent developments in the field of semimagnetic IV_VI semiconduc- tors are discussed with the emphasis on magnetic properties of bulk crys- tals with rare-earth ions (e.g., Sn1-x Gd_xTe, Pb1-x Ce_xSe, Pb1-x Eu_xTe)and new low-dimensional magnetic multilayers(PbTe-EuTe and PbS-EuS). The other issues addressed, concern the new results in transport properties of ferromagnetic Pb_1-x-y Sn_y Mm_x Te, the observation of the Knight shift in electron paramagnetic resonance in PbTe:Mn and SuTe:Mn, and the ther- moelectric properties of PbTe-Pb_1-x Eu_xTe quantum wells.
