Annealing-Dependent Magnetic Depth Profile in Ga[1-x]Mn[x]As
B. J. Kirby, J. A. Borchers, J. J. Rhyne +7
We have studied the depth-dependent magnetic and structural properties of as-grown and optimally annealed Ga[1-x]Mn[x]As films using polarized neutron reflectometry. In addition to…
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…
The Effect of Mn Interstitials on the Lattice Parameter of Ga(1-x)Mn(x)As
I. Kuryliszyn-Kudelska, J. Z. Domagala, T. Wojtowicz +4
Structural investigation of as-grown as well as annealed Ga(1-x)Mn(x)As epilayers was carried out using high resolution X-ray diffraction (XRD) measurements for a wide range of Mn…
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…
Collective character of spin excitations in a system of Mn spins coupled to a two-dimensional electron gas
F. J. Teran, M. Potemski, D. K. Maude +7
We have studied the low energy spin excitations in n-type CdMnTe based dilute magnetic semiconductor quantum wells. For magnetic fields for which the energies for the excitation of…
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…
