The Embedded System

The structural, transport, electronic structure and magnetic properties of NdFe 1-x Ni x O 3(x = 0.4, 0.5) samples are studied. Both the samples are in single phase with orthorhombic Pbnm structure. The transport properties show the semiconducting nature of the system and no transition is seen on the application of magnetic field. The electronic structure studies verify the chemical states of the ions in the embedded system and the symmetry of the interacting ions. The magnetic properties show the transition from ferromagnetic to paramagnetic phase and which is studied through the Mossbauer studies. The paramagnetic doublet in the x = 0.5 system clearly shows the phase transition from ferromagnetic to paramagnetic.

Lmto Method

First principles calculations are performed using a tight-binding linear muffin-tin orbital (TB-LMTO) method with local density approximation (LDA) and atomic sphere approximation (ASA) to understand the electronic properties of transition metal hydrides (TMH) (TM = Cr, Mn, Fe, Co). The structural property, electronic structure, and magnetic properties are investigated. A pressure induced structural phase transition from cubic to hexagonal phase is predicted at the pressures of 50 GPa for CrH and 23 GPa for CoH. Also, magnetic phase transition is observed in FeH and CoH at the pressures of 10 GPa and 180 GPa, respectively.

Strategic Resource

Rare earth is an important strategic resource in China, and it has the reputation of “industrial vitamin” in the industrial field. Rare earth is non-renewable. Due to the diverse preparation methods of rare earth oxides, different preparation methods have their own advantages and disadvantages. Using different methods to prepare nano-rare earth oxides. And because of the special electronic structure of rare earth elements, it has special optical, electrical and magnetic properties. This article mainly introduces the use of nano-rare earth oxides in luminescence, permanent magnetism, ceramics, catalysis and so on.
