A La0.67Ca0.33MnO3−δ alloy was produced via a low-temperature solid state reaction in a high-energy ball mill. The milled alloy is found to exhibit the paramagnetic-to-ferromagnetic (P–F) transition at 150 K. However, the widely reported insulat

Studies of atomic correlations in quaternary semiconductor alloys using the extended X-ray absorption fine structure technique

Autor: Shaheen M. Islam, Bruce A. Bunker

Publikováno v: Physics Letters A. 156:247-252

The local structure of a III–V quaternary alloy, GaxIn1-xAsySb1-y, has been determined using the EXAFS technique. Our measurements show a consistent deviation of nearest-neighbor occupation from randomness with GaAs pairs being clearly preferred

Cation engineering of Cu-ferrite films deposited by alternating target laser ablation deposition

Autor: Aria Yang, C. Vittoria, Shaheen M. Islam, Zhaohui Chen, Vincent G. Harris

Publikováno v: Journal of Applied Physics. 103:07E509

Epitaxial copper ferrite thin films were deposited on MgO substrates by the alternating target laser ablation deposition method. A series of films was studied to explore the impact of oxygen operating pressure, substrate temperature, and the ratio of

Study of the local structure of GaxIn1−xAsySb1−y, a quaternary III–V semiconductor alloy, using extended x-ray absorption fine structure (EXAFS) technique

Autor: Bruce A. Bunker, Shaheen M. Islam

Publikováno v: Physica B: Condensed Matter. 158:606-607

Using the extended x-ray absorption fine structure (EXAFS) technique, we have investigated the local structure of the quaternary alloy series Ga x In 1− x As y Sb 1− y . Our measurements reveal the types of atoms about the “average” As atom a
