Lutetium-doped EuO films grown by molecular-beam epitaxy

Low-damping sub-10-nm thin films of lutetium iron garnet grown by molecular-beam epitaxy

We analyze the structural and magnetic characteristics of (111)-oriented lutetium iron garnet (Lu3Fe5O12) films grown by molecular-beam epitaxy, for films as thin as 2.8 nm. Thicknessdependent measurements of the inand out-of-plane ferromagnetic resonance allow us to quantify the effects of two-magnon scattering, along with the surface anisotropy and the saturation magnetization. We achieve eff...

High-mobility thin InSb films grown by molecular beam epitaxy

The problem of preparing high-mobility thin InSb films is revisited for magnetoresistive and spintronic sensor applications. We introduce a growth process that significantly improves the electrical properties of thin unintentionally doped InSb layers ~60–300 nm! epitaxially grown on GaAs~100! substrates by reducing the density of dislocations within the interfacial layer. The epilayer propertie...

Epitaxial Mn-doped ZnO diluted magnetic semiconductor thin films grown by plasma-assisted molecular-beam epitaxy

A growthwindow for theMn effusion cell temperature (TMn) is demonstrated for epitaxialMn-doped ZnO (MnZnO) thin films grown on sapphire substrates using molecular-beam epitaxy. Within the growth window, the films are ferromagnetic with the largest saturated magnetization occurring at TMn1⁄4700 1C. The Curie temperature of these MnZnO diluted magnetic semiconductor thin films is above roomtemper...

Ga-Doped ZnO Films Grown on GaN Templates by Plasma-Assisted Molecular-Beam Epitaxy

Atmospheric oxygen in Mn doped GaAs/GaAs(0 0 1) thin films grown by molecular beam epitaxy

Mn doped GaAs thin films were grown using molecular beam epitaxy at high and low substrate temperatures. The elemental concentration depth profiles in the thin films were determined by using Auger electron spectroscopy combined with ion etching. The Mn concentration is higher near the surface and then decreases with depth for films grown at high substrate temperatures. The Mn concentration prof...
