The effect of temperature variation on the magnetoelasticproperties of the CoAlxFe2−xO4 system (for x=0.0, 0.2, 05, and 0.7) has been studied. Substitution of Al3+ for Fe3+ was found to lower the Curie temperature of the samples and to change the lattice parameter. The magnitude of peak to peak magnetostriction, strain sensitivity, magnetomechanical hysteresis, and relative contributions of λ111 and λ100 to the resultant magnetostriction were found to vary with temperature. The results show the possibility of tailoring the magnetoelasticproperties of highly magnetostrictive cobalt ferrite at temperatures of interest by cation substitution.

Fossil fuels, such as coal and natural gas, currently play an enormous role in our nation's base-load energy supply and provide reliable domestic energy security. If fossil fuels are to remain a component of future energy production in a carbon constrained world, then carbon-neutral energy options must be available. With fossil fuels, point-source environmental control technologies will be required to help comply with future carbon dioxide (CO2) emissions standards. One very promising technology, carbon capture and storage (CCS), consists of the separation of CO2 from the products of combustion of fossil fuels or from fuel gas produced by gasification of …
