Magnetic disaccommodation is investigated for ferrous ferrites with normal spinel structure. This study shows the presence of a new relaxation process in the temperature region IV (285 K) that has not been detected in inverse spinels. A numerical analysis of the isochronal spectra reveals that it ...
But if you pour (or even drip) water into a container of molten metal, it's a different story: That is quite likely to cause a steam explosion that throws liquid metal all over. So when you're pouring metal into water, the biggest danger is if any water happens to splash back into ...
Magnetic dynamics of Zn/sup 57/Fe/sub 2/O/sub 4/ nanoparticles dispersed in a ZnO matrix The magnetic properties of diluted ZnFe/sub 2/O/sub 4/ nanoparticles with nearly normal spinel structure, dispersed in a nonmagnetic ZnO matrix, are presen... Goya,F G. - 《IEEE Transactions on Ma...
The carbonated “solidus ledge” is a relatively narrow boundary in the lithospheric mantle capable of an abrupt immobilisation of fluxing or transported carbonated melts. The investigated rocks are estimated to store approximately 0.02 kg C/m3 (or 6 ppm C) occurring as carbonates in the MSI....
The space between the adjacent atoms in the interface of the zigzag structure increases, which is larger than that of the normal region away from the interface. Therefore, the enlarged space of the zigzag structure in the interface can accommodate trivalent cations with a larger ionic radius. ...

Walter. (1998) suggested that the Al2O3 contents of peridotites decrease with increasing degrees of partial melting because Al2O3 is mainly hosted in silicate minerals such as pyroxene, spinel, and amphibole. This is consistent with that the proportion of amphibole in the Kohistan samples ...
From a normal coordinate analysis of resonance Raman data obtained for 1, a value of kNi-C = 1.44 mdyn/Å is obtained for the Ni−C stretch force constant of this species. This value is smaller than kCo-C = 1.85 mdyn/Å, which is reported for the Co−C stretch in the ...
(a bottom-up process) and depended on the amount of laser energy or wavelength. According to our findings, laser ablation combined top-down and bottom-up methodologies. The NPs produced by this method turned out to be a cubic inverse spinel structure packed in such a way that they were ...
The olivine rims from southern African kimberlites have δ18O values that are intermediate to those of high-Mg and low-Mg olivine cores. Despite the large variability, from 3.99 ± 0.33‰ (2σ) to 6.31 ± 0.30‰ (2σ), these analyses show a quasi-normal distribution, with an...
