Structural and magnetic properties of Ce-doped strontium hexaferrite
TL;DR: In this article, the authors used X-ray diffraction (XRD), photoluminescence (PLS), scanning electron microscopy (SEM), elemental mapping (EDS), TEM and vibrating sample magnetometer (VSM) at 300 and 10'K. All the elaborated products presented typically squarness ratio (M r /M s ) around 0.5, indicating the existence of noninteracting single domain MNPs with a uniaxial anisotropy.

Vegard's law.
Alan R. Denton,N. W. Ashcroft +1 more
TL;DR: Applications of a density-functional theory of nonuniform fluid mixtures to the fluid-solid transition of simple binary mixtures of hard spheres demonstrates the importance of relative atomic sizes in determining lattice constants and suggests that for sufficiently small disparities in atomic size Vegard's law may also hold along the fluid -solid coexistence curve.

Luminescence and Photocatalytic Activity of ZnO Nanocrystals: Correlation between Structure and Property
Yuanhui Zheng,Chongqi Chen,Yingying Zhan,Xingyi Lin,Qi Zheng,Kemei Wei,Jiefang Zhu,Ying-Jie Zhu +7 more
TL;DR: The results show that the aspect ratio and size of the as-synthesized ZnO nanocrystals increase with increasing [OH-]/[Zn2+]; the morphology evolves from nanorod to nanoparticle with an increase in the annealing temperature; the BET surface areas of the corresponding samples decrease during these processes, respectively.

Temperature dependence of electrical properties of nickel–zinc ferrites processed by the citrate precursor technique
TL;DR: In this article, temperature dependence of resistivity, dielectric constant and Dielectric loss have been investigated for four different compositions of nickel-zinc ferrites, Nii_IZnIFe2O4 (x = 0.2, 0.5 and 0.6), prepared by the citrate precursor technique, and the variations in activation energy with composition and sintering temperature were explained on the basis of the site occupancy in ferrites and the atomic radii of the constituent metal ions.
