Mixed ferrites Sm0.5Pr0.5FeO3 and Sm0.5Nd0.5FeO3 with orthorhombic perovskite structure isotypic with GdFeO3 were synthesized by solid-state reaction technique in air at 1473 K. Structural parameters obtained at room temperature prove a formation of continuous solid solutions in the SmFeO3-PrFeO3 and SmFeO3-NdFeO3 pseudo-binary systems. Sm0.5Pr0.5FeO3 and Sm0.5Nd0.5FeO3 show strongly anisotropi...

In this work, orthoferrite NdFeO3 nanomaterials with particle sizes 20-40 nm have been successfully synthesized via a simple co-precipitation method through the hydrolysis of Nd (III) and Fe cations in hot water 5% NaOH as precipitating agent. Single-phase was generated after calcination as-prepared powder at 700, 800, 900 °C for 1 hour. The UV-Vis spectra room temperature presented strong abso...

Scrutiny of an established monoclinic magnetic space group for NdFeO3 reveals hitherto unknown properties the orthoferrite. Future experiments using neutron and x-ray diffraction techniques can verify them. Neodymium ions possess Dirac multipoles, both time-odd (magnetic) parity-odd (polar), that come with unique conditions. Non-magnetic polar Nd multipoles are permitted even though is centrosy...

Article history: Received 18 May 2016 Received in revised form 23 September 2016 Accepted 3 October 2016 Available online 4 October 2016 Thin films were deposited on Pt/Ti/SiO2/Si substrates using pulsed laser deposition from a target with a composition (Bi0.825Nd0.175Fe0.97Ti0.03O3) with 5 mol% excess Bi2O3 within the antiferroelectric (AFE) region of the NdFeO3-BiFeO3 phase diagram. However, ...

The pretreatment processes consisting of grinding followed by roasting were investigated to improve the selective leaching of Nd and Dy from neodymium-iron-boron (NdFeB) magnet scraps. The peaks of Nd(OH)3 and Fe were observed in XRD results after grinding with NaOH as the amount of water addition increased to 5 cm. These results indicate that the components of Nd and Fe in NdFeB magnet could b...
