چکیده
Tetragonal distorted spinel of CuMn2−xTixO4 (x = 0, 0.25 and 0.50) was prepared by solid state reaction method followed neutron diffraction, FTIR spectroscopy, dielectric spectroscopy magnetic measurements. The confirmation regarding phase formation identification additional has been carried out analysing the room temperature diffraction. Besides, data have also assisted in ascertaining these results. Then, susceptibility study CuMn2O4 shows clearly ferrimagnetic order below 76 K associated with meta-magnetic which turns into spin-glass behaviour CuMn1.50Ti0.50O4. In addition, M(H) all spinels are described Arrot’s plot for weak ferromagnetism. Further, abrupt change due to Ti-substitution at is analysed electrical property using complex

Ti substitution for Mn in MnCoGe - The magnetism of Mn0.9Ti0.1CoGe
Bulk magnetization measurements (5-320 K; 0-8T) reveal that below room temperature Mn0.9Ti0.1CoGe exhibits two magnetic phase transitions at ~178 K and ~280 K. Neutron diffraction measurements (3-350K) confirm that the transition at ~178K is due to the structural change from the low-temperature orthorhombic TiNiSi-type structure to the higher temperature hexagonal Ni2In-type structure while the...
متن کاملCrossover from Spin-Density-Wave to Neel-like Ground State
The characterization and evolution of a Spin Density Wave into the Quantum Neel ground state is considered in the context of a weak coupling theory of the half-filled Hubbard model. Magnetic properties obtained from this weak coupling approach in one dimension compare favorably with exact results from Bethe ansatz (BA). A study of the evolution of several length scales from weak to strong coupl...

Birnessite compounds are stable across a wide range of compositions that produces a remarkable diversity in their physical, electrochemical and functional properties. These are hydrated analogues of the magnetically frustrated, mixed-valent manganese oxide structures, with general formula, NaxMnO2. Here we demonstrate that the direct hydration of layered rock-salt type αNaMnO2, with the geometr...
متن کاملManipulating charge transfer excited state relaxation and spin crossover in iron coordination complexes with ligand substitution.
Developing light-harvesting and photocatalytic molecules made with iron could provide a cost effective, scalable, and environmentally benign path for solar energy conversion. To date these developments have been limited by the sub-picosecond metal-to-ligand charge transfer (MLCT) electronic excited state lifetime of iron based complexes due to spin crossover - the extremely fast intersystem cro...
