Fully epitaxial C1b-type NiMnSb half-Heusler alloy films for current-perpendicular-to-plane giant magnetoresistance devices with a Ag spacer
Remarkable magnetic and spin-dependent transport properties arise from well-designed spintronic materials and heterostructures. Half-metallic Heusler alloys with high spin polarization exhibit properties that are particularly advantageous for the development of high-performance spintronic devices. Here, we report fully (001)-epitaxial growth of a high-quality half-metallic NiMnSb half-Heusler a...
متن کاملThe surface composition and spin polarization of NiMnSb epitaxial thin films
– The composition in the surface region of the Heusler alloy NiMnSb has been studied using angle-resolved X-ray photoemission spectroscopy, low-energy electron diffraction and spin-polarized inverse photoemission. The results are consistent with a generally Mn-Sb terminal layer, though the surface composition is very sensitive to preparation. The surface composition has a critical influence on ...
متن کاملEpitaxial growth and surface properties of half-metal NiMnSb films.
We present, herein, an extended study of the half-Heusler alloy NiMnSb, starting with the deposition technique, continuing with the basic structural and magnetic properties of the thin films, and finishing with the electronic and compositional properties of their surfaces. The experimental methods we apply combine magnetization and magnetoresistivity measurements, atomic force microscopy, ferro...
متن کاملInfrared probe of the electronic structure and carrier scattering in NiMnSb thin films
We report the use of infrared reflectance spectroscopy to examine the electronic structure of epitaxial, sputter deposited thin films of the predicted half-metallic ferromagnet NiMnSb. The contribution of the interband transitions to the optical conductivity, as well as the spectral weight of conducting carriers, agree with the band structure calculations predicting a half-metallic state in NiM...
متن کاملScanning tunneling microscopy studies of temperature-dependent etching of diamond (100) by atomic hydrogen.
We present a technique for obtaining atomic resolution ultrahigh vacuum scanning tunneling microscopy images of diamond (100) films, and use this technique to study the temperature dependence of the etching of epitaxial diamond (100) films by atomic hydrogen. We find that etching by atomic hydrogen is highly temperature dependent, resulting in a rough and pitted surface at T approximately 200 a...
