  3. We have investigated transport properties of electrons in magnetic quantum structures under an applied constant electric field. the transmission coefficient and current density have been calculated for electron tunneling through structures consisting of identical magnetic barriers and magnetic wells and structures consisting of unidentical magnetic barriers and magnetic wells. it is shown that the transmission coefficient of electrons in a wider nonresonance energy region is enhanced under an applied electric field. the resonance is suppressed for electron tunneling through double - barrier magnetic ( dbm ) structures arranged with identical magnetic barriers and magnetic wells. incomplete resonance at zero bias is changed to complete resonance at proper bias for electron tunneling through dbm structures arranged with different magnetic barriers and magnetic wells. the results also indicate that there exist negative conductivity and noticeable size effect in dbm structures

    對磁量子結構中電子在外加恆定電場下的輸運性質進行了研究.分別計算了電子隧穿相同磁壘磁阱和不同磁壘磁阱構成的兩種磁量子結構的傳輸概率和電流密度.計算結果表明，在相當寬廣的非共振電子入射能區，外加電場下電子的傳輸概率比無電場時增加.對于電子隧穿相同磁壘磁阱構成的雙磁壘結構，共振減弱；對于電子隧穿不同磁壘磁阱構成的雙磁壘結構，無電場作用時的非完全共振在適當的偏置電壓下轉化為完全共振，這時的電子可實現理想的共振隧穿.研究同時表明，磁量子結構中存在著顯著的量子尺寸效應和負微分電導
