External control of the direction of magnetization in ferromagnetic InMnAs/GaSb heterostructures
X. Liu, W. L. Lim, L. V. Titova +10
In this paper, we demonstrate external control over the magnetization direction in ferromagnetic (FM) In_{1-x}Mn_{x}As/GaSb heterostructures. FM ordering with T_C as high as 50 K i…

Growth and properties of ferromagnetic In(1-x)Mn(x)Sb alloys
T. Wojtowicz, W. L. Lim, X. Liu +15
We discuss a new narrow-gap ferromagnetic (FM) semiconductor alloy, In(1-x)Mn(x)Sb, and its growth by low-temperature molecular-beam epitaxy. The magnetic properties were investiga…

Enhancement of Curie temperature in Ga(1-x)Mn(x)As/Ga(1-y)Al(y)As ferromagnetic heterostructures by Be modulation doping
T. Wojtowicz, W. L. Lim, X. Liu +6
The effect of modulation doping by Be on the ferromagnetic properties of Ga(1-x)Mn(x)As is investigated in Ga(1-x)Mn(x)As/Ga(1-y)Al(y)As heterojunctions and quantum wells. Introduc…
