“…The size dependence can give rise to the magnetic properties of the material due to the various effects such as the influence of surface, the onset of carrier confinement, and the reduction in structure size below that of a single magnetic domain [ 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. The magnetic properties of InP with 1D nanostructures doped by TM elements have been investigated for the application of nano-scale spintronics devices [ 19 , 20 , 21 , 22 ]. However, for applications in practical spintronic devices, a lot of research of InP based on DMS is needed.…”

InZnP:Ag nano-rods fabricated by the ion milling method were thermally annealed in the 250~350 °C temperature range and investigated the optimum thermal annealing conditions to further understand the mutual correlation between the optical properties and the microscopic magnetic properties. The formation of InZnP:Ag nano-rods was determined from transmission electron microscopy (TEM), total reflectivity and Raman scattering analyses. The downward shifts of peak position for LO and TO modes in the Raman spectrum are indicative of the production of Ag ion-induced strain during the annealing process of the InZnP:Ag nano-rod samples. The appearance of two emission peaks of both (A0 X) and (e, Ag) in the PL spectrum indicated that acceptor states by Ag diffusion are visible due to the effective incorporation of Ag-creating acceptor states. The binding energy between the acceptor and the exciton measured as a function of temperature was found to be 21.2 meV for the sample annealed at 300 °C. The noticeable MFM image contrast and the clear change in the MFM phase with the scanning distance indicate the formation of the ferromagnetic spin coupling interaction on the surface of InZnP:Ag nano-rods by Ag diffusion. This study suggests that the InZnP:Ag nano-rods should be a potential candidate for the application of spintronic devices.

“…In addition to exhibiting large anisotropy, 1D magnetic nanostructures can act as their own interconnects, making them attractive for use in sensing and as active elements in spintronic devices. The magnetic properties of InP based on 1D nanostructures doped with TM elements have been studied for the application of nanoscale spintronic devices [12,[20][21][22]. However, further investigations of 1D nanostructure InP-based DMSs reveal that we still require great ingenuity to realize their application in practical spintonic devices.…”

The formation including density, and height of InFeP:Ag nano-rods doped with noble metal Ag using ion milling method was preponderantly determined from TEM and XRD analyses. We investigate especially the enhanced ferromagnetism of the well aligned InFeP:Ag nano-rods. AES and XPS measurements were carried out in order to investigate the incorporation of Ag and to verify the local chemical bonding of InFeP:Ag nano-rods. The variation of FWHM for DCRC and TAD peaks demonstrates that noble metal Ag is incorporated into InFeP:Ag nano-rods. The noticeable ferromagnetic signature (M-H curve) of the InFeP:Ag nano-rods is observed and Tc persists up to near 350 K (3.9 × 10-4 emu/g) from temperature - dependence magnetization (M-T curve) measurements. This study suggests that the InFeP:Ag nano-rods should be a potential candidate for the application of spintronic devices.

The present work is a comprehensive analysis of the electronic and magnetic properties of pristine and Mn-doped GaN nanowires (NWs) using first-principles calculations. The investigations were performed by considering the effects of size, shape, and passivation on GaN NWs oriented in three different crystallographic growth directions, namely [0001], 11 20 ½ , and 1 100 ½ . Binding energy calculations predict that the stability increases with the size of NWs with and without passivation. Formation energy shows that surface (core) position is energetically suitable for substitutional Mn doping in unpassivated (passivated) NWs. We found that [0001]orientated GaN NW is most energetically favorable and 1 100 ½ -orientated GaN NW is most suitable for substitutional doping. Mn doping causes the localization of energy states in the vicinity of the Fermi level and enhances the metallicity in the NWs. It is revealed that NWs retain their electronic nature even after doping, except for square-shaped 11 20 ½ -oriented NW. The spin-polarized electronic properties were also calculated for Mn-doped NW. The result shows a unique halfmetallicity in square-shaped NW oriented along the 1 100 ½ direction. The energetic stability of [0001]-oriented GaN NW and the electronic behavior of unpassivated 1 100 ½ -oriented GaN NW can be useful as an interconnection between nanoelectronic devices and spin-based applications.
