TL;DR: Powder X-ray diffraction data confirms the formation of a single phase wurtzite type ZnO structure for all the compositions andoretical studies using density functional calculations suggest that the partial occupancy of S2 states leads to an increased double exchange interaction favoring the ferromagnetic ground states.

TL;DR: In this article, the magnetic properties of CuO-ZnO heterostructures were investigated to elucidate the origin of the ferromagnetic signature in Cu doped ZnO.

TL;DR: In this paper, the role of Ho substitution in magnetite nanoparticles, which is found to enhance the KV product arising from the large anisotropy of Ho3+ moments, was investigated.

TL;DR: In this article, the synthesis of rod shaped Mn (2.2 ) doped ZnO single crystals using the surfactant AOT (sodium bis (2-ethylhexyl) sulpho succinate) assisted solid-state synthesis route was reported.

TL;DR: In this article, the growth of acicular hydrogoethite particle proceeds by the oxidation of Fe(OH) 2 · x H 2 O to an intermediate phase through the nucleation within the amorphous ferric oxy-hydroxide [FeO x (OH) 3−2 x · y h 2 O] and growth of α-FeOOH·(H 2 O) x acicular particles with the aid of morphology controlling agents, as evidenced from X-ray diffraction and transmission electron microscope (TEM) studies.
