Structural phase transition driven by spin-lattice interaction in a quasi-one-dimensional spin system of [1-(4'-Iodobenzyl)pyridinium][Ni(mnt)(sub 2)]

Article Abstract:

Crystal structures and magnetic properties are determined for two novel compounds, [1-(4'-iodobenzyl)-pyridinium][M(mnt)(sub 2)] (mnt(super 2-) = maleonitriledithiolate, M = Ni (1) or Cu (2)). It is concluded that the structural transition of M=Ni is driven by spin-lattice interaction, as crystal Cu (S = 0) does not exhibit a structural transition.

Size-dependent orientation growth of large-area ordered Ni nanowire arrays

Article Abstract:

Large-area ordered Ni nanowire arrays with different diameters are fabricated by the direct current electrodeposition into the holes of porous anodic alumina membrane. The results indicate that the growth orientation of Ni nanowires turns from [110] to [111] direction with increasing diameters of nanowires.

Effects of Ni doping on [MnO6] octahedron in LiMn2O4

Article Abstract:

LiNi(sub x)Mn2-xO4 (x less than or equal to 0.5) powders were synthesized using a sol-gel technique. It was found that partial Ni atoms occupy the 8a sites in heavy doped LiNi(sub x)Mn2-xO4 via X-ray diffraction.
