Automated NanoSIMS Measurements of Spinel Stardust from the Murray Meteorite

open access: yes, 2010
We report new O isotopic data on 41 presolar oxide grains, 38 MgAl2O4 (spinel) and 3 Al2O3 from the CM2 meteorite Murray, identified with a recently developed automated measurement system for the NanoSIMS.

Synthesis of zinc ferrite nanopowders in an RF thermal plasma [PDF]

open access: yes, 2001
Nanosized zinc ferrite spinel powders of various compositions were produced in an RF thermal plasma from oxide mixtures and from co-precipitated hydroxides. The products were characterised for bulk chemical (ICP-AES), and phase composition (XRD).

Thermodynamic Properties of MgAl2O4 Spinel at High Temperatures and High Pressures

open access: yesCrystals, 2023
Thermodynamic properties of MgAl2O4 spinel are significant in understanding the phase relations of the Earth’s crust and upper mantle, but available values from experimental measurements are limited at ambient pressure conditions to date.

Patterned ferrimagnetic thin films of spinel ferrites obtained directly by laser irradiation [PDF]

open access: yes, 2013
Some spinel ferrites can be oxidized or transformed at moderate temperatures. Such modifications werecarried out on thin films of mixed cobalt copper ferrites and maghemite, by heating small regions with alow-power laser spot applied for about 100 ns ...
