AB  - In this work we show the size-dependent ferromagnetic behavior of undoped and Mndoped PZN-4.5PT single crystals, consequently their multiferroic one Undoped single crystals were tamisized and three different sizes powders were investigated showing a size dependence in such ferroelectric materials while no magnetism is observed for the non-oriented and oriented bulk single crystals. The results show the existence of an optimized grain sizes range (45 μm . D . 63 μm) in which the magnetism is the highest (around 0.08 emu/g). It is found that the maximum value of the relative strain decreases from 0.25% for undoped crystals to 0.20% for Mn-doped ones. The remanent magnetization Mr and coercivity (Hc) were found equal, respectively, to 2×10-4 emu/g and 63 Oe for undoped and, 7×10-4 emu/g and 66 Oe for Mn-doped PZN-4.5PT, indicating that PZN-4.5PT particles possessed weak ferromagnetic behavior. Mn doping increases highly the spontaneous magnetization from 7.5 × 10-3 emu/g to 1.0×10-3 emu/g, respectively for undoped and Mn-doped nanoparticles. © 2019 EPLA.

AB  - Investigation and synthesis of anisotropic magnetic nanostructures, such as wires, rods, fibers, tubes and chains, is an important field of research due to the beneficial properties and great potential for practical applications ranging from magnetic data storage to biomedicine. Silica coated iron oxide nanochains of length up to 1 μm and diameter ∼80–100 nm have been synthesized by the simultaneous magnetic assembly of superparamagnetic iron oxide nanoparticle clusters (SNCs) as links (viz. maghemite, γ-Fe2O3) and the fixation of the assembled SNCs with an additional layer of deposited silica. We reveal that is possible to achieve either superparamagnetic or ferromagnetic behavior with the nanochains depending only on their physical orientation. The superparamagnetic behavior is observed for random orientation of nanochains whereas ferromagnetic properties (HC ≈ 100 Oe) come to the fore when the orientation is mainly parallel. These peculiar magnetic properties can be related to: (1) the specific size, which is ∼9 nm, of primary building blocks of the nanochains, i.e. of maghemite nanoparticles; (2) to the anisotropic chain-like shape of the particles; and (3) to inter-particle interactions. Large pore volume and pore size of silica shell as well as good colloidal stability and magnetic responsiveness of such nanochains enable applications in biomedicine. © 2019 Elsevier B.V.
