Spin waves in magnetic quantum wells with Coulomb interaction and $sd$ exchange coupling
Spin waves magnetic quantum wells Coulomb interaction
2010/11/24
We theoretically describe the spin excitation spectrum of a two dimensional electron gas embedded in a quantum well with localized magnetic impurities. Compared to the previous work,
we introduce equ...

Effects of Disorder on the Exchange Coupling in (Ga,Mn)As Diluted Magnetic Semiconductors
Disorder Exchange coupling Diluted magnetic semiconductors
2010/8/26
A theoretical study of the effects of disorder on the Mn-Mn exchange interactions for Ga1¡xMnxAs diluted magnetic semiconductors is presented. The disorder is intrinsically considered in the cal...
