Perpendicular magnetic anisotropy in Ta|Co40Fe40B20|MgAl2O4 structures and perpendicular CoFeB|MgAl2O4|CoFeB magnetic tunnel junction

, 2014
Magnetic properties of Co40Fe40B20(CoFeB) thin films sandwiched between Ta and MgAl2O4layers have been systematically studied. For as-grown state, Ta/CoFeB/MgAl2O4structures exhibit good perpendicular magnetic anisotropy (PMA) with interface anisotropy ...

STRUCTURAL AND PHOTOLUMINESCENCE CHARACTERIZATION OF MgAl2O4:Eu PHOSPHOR SYNTHESIZED BY COMBUSTION METHOD.

, 2017
The MgAl2O4 spinel doped with Eu2+ ions powder phosphor was prepared at temperature as low as 500 oC using the combustion route. A structural property of the powder was characterized by X-ray diffraction (XRD).

Thermoluminescent processes of MgAl2O4 irradiated at room temperature.

Physical review. B, Condensed matter, 1991
Two non-first-order kinetic peaks at about 350 and 500 K appear in the thermoluminescence (TL) spectra of single-crystal and polycrystalline MgAl2O4 irradiated with ionizing radiation at room temperature. Among others, emission from Cr3+ and Mn2+ ions are observed.
