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.
