The magnetostructural coupling between the structural and magnetic transition has a crucial role in magnetoresponsive effects martensitic-transition system. A combination of various based on this may facilitate multifunctional applications host material. Here we demonstrate feasibility obtaining stable over broad temperature window from 350 to 70 K, with tunable effects, MnNiGe:Fe alloys. alloy exhibits magnetic-field-induced martensitic paramagnetic austenite ferromagnetic martensite....
Using first-principles calculations, we investigate the band structures of a series quaternary LiMgPdSn-type Heusler compounds. Our calculation results show that five compounds CoFeMnSi, CoFeCrAl, CoMnCrSi, CoFeVSi and FeMnCrSb possess unique electronic characterized by half-metallic gap in one spin direction while zero-width other showing gapless semiconducting behavior. We further analysis magnetic properties all alloys involved, reveal semi-empirical general rule (total valence electrons...
The elastic properties, phase stability, and magnetism correlations among them in all-$d\text{\ensuremath{-}}\mathrm{metal}$ Heusler compounds, i.e., ${\mathrm{Ni}}_{2}\mathrm{Mn}T$ ($T=\mathrm{Sc}$, Ti, V, Cr, Y, Zr, Nb, Mo, Hf, Ta, W) were systematically investigated by first-principles calculations. results indicated that compounds not fully consistent with the conventional atomic preferential occupation rule family. Within scope of structures, containing early transition metal atoms...
Taking Cu-doped Ni 2 MnGa alloys as an example, the unified physical mechanism for martensitic phase transition and ductility in Ni–Mn-based ferromagnetic shape memory was investigated theoretically.
Nanotubes of metal-free 5,10,15,20-tetrakis(4-chlorophenyl)porphyrin (H2TClPP) are fabricated by using nanoporous anodized aluminum oxide (AAO) membrane as the template. The morphology and structure nanotubes investigated transmission electron microscopy (TEM) field emission scanning (FESEM). It is found that outer diameter matches well with pore AAO membranes, interestingly, porphyrin molecules packed orderly within nanotube walls. properties H2TClPP have been UV-vis absorption spectroscopy...
Polyaniline (PANI)/multiwalled carbon nanotube (MWNT) composites with a uniform tubular structure were prepared from in situ polymerization by dissolving amino-functionalized MWNT (a-MWNT) aniline monomer. For this the oxidized multiwalled was functionalized ethylenediamine, which provided ethylenediamine functional group on surface confirmed Fourier-transform infrared spectra (FT-IR). The a-MWNT dissolved monomer, and of presence these well dispersed nanotubes yielded novel composite having...
The structure, magnetism, magnetic compensation behavior, exchange interaction and electronic structures of Co50-xMn25Ga25+x Co50-xMn25+xGa25 (x=0-25) alloys have been systematically investigated by both experiments first-principles calculations. We found that all the samples exhibited body centered cubic with a high degree atomic ordering. With increasing Ga content, composition dependence lattice parameters shows kink point at middle in alloys, which can be attributed to enhanced covalent...
In this study, the all-d-metal Heusler compounds Ni2MnT (T = Sc, Ti, V, Cr, Y, Zr, Nb, Mo, Hf, Ta, and W) were considered as representative examples, magnetism-dependent martensitic phase transition was systematically investigated by first-principles calculations. Comparative analysis of calculated magnetic states-dependent elastic parameters, electronic structures, thermodynamic parameters indicates that weakly with late metal atoms show higher possibilities transition. Although magnetism...
The strong coupling between the crystal structure and magnetic state (ferromagnetic or helical antiferromagnetic) of ${\mathrm{FeMnP}}_{0.75}{\mathrm{Si}}_{0.25}$ is investigated using density functional theory in combination with atomistic spin dynamics. We find many competing energy minima for drastically different ferromagnetic noncollinear configurations. also that appearance a spin-spiral at finite temperature strongly related to one structures reported this material. Shorter Fe-Fe...
The lattice dynamics, elastic properties and the origin of vanished magnetism in equiatomic quaternary Heusler compounds CoMnV Z ( = Al, Ga) are investigated by first principle calculations this work. Due to similar constituent atoms CoMnVAl CoMnVGa compounds, they both stable LiMgPdSn-type structure with comparable size, phonon dispersions electronic structures. Comparatively, we find that is more structurally than CoMnVGa. Meanwhile, increased covalent bonding component enhances its...
The metastable spin gapless semiconductor Ti 2 MnAl results from the kinetic arrest of atomic diffusion during sample preparation high-temperature relatively low-symmetric phase to low-temperature high-symmetric phase.
The magnetic state of the FeMnP0.75Si0.25 alloy was investigated by first principles calculations. coexistence ferromagnetic and antiferromagnetic phases in with same hexagonal crystal structure revealed. It found that kinetic arrest during transition from high temperature disordered paramagnetic phase to low ordered results intermediate metastable partially phase.
