The synthesized samples were characterized using X-ray diffraction (XRD), Raman spectroscopy, atomic force microscopy (AFM), vibrating sample magnetometer (VSM), and magnetoresistance (MR) measurements. Raman analysis revealed the presence of 1LO mode for pure Ni/NiO and 2LO mode for Mn-doped Ni/NiO. AFM images confirmed uniform and densely packed grains with root-mean-square (RMS) roughness values ranging from 23 to 32 nm. The 2% Mn-doped Ni/NiO nanostructures exhibit enhanced ferromagnetism with a blocking temperature around 200 K, as revealed by ZFC-FC bifurcation. Magnetic hysteresis loops confirm zero coercivity and no remanence, indicating soft ferromagnetic behaviour with superparamagnetic-like relaxation. The MR of 2% Mn-doped Ni/NiO nanocomposites was investigated over a wide temperature range (2–300 K). All samples exhibited negative MR due to suppression of AFM domains and enhanced FM ordering, with a maximum value of -0.40% at 300 K, while pure Ni/NiO showed a higher MR of -0.6%. The observed negative magnetoresistance and butterfly-like hysteresis are directly correlated with the coexistence of ferromagnetic Ni and antiferromagnetic NiO phases, where spin-dependent scattering and domain wall dynamics govern the transport behavior. Fitting of the resistivity to a Bloch-Grüneisen and Fermi liquid (T²) model yields a nearly field-independent Debye temperature (<span>(:{{Theta:}}_{D})</span>≈303–320 K). Doping significantly enhances the residual resistivity and electron-phonon scattering coefficient, consistent with stronger disorder scattering.</p></div>","PeriodicalId":669,"journal":{"name":"Journal of Superconductivity and Novel Magnetism","volume":"39 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148751489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The KSEA interaction introduces a distinct effect that slows the thermal decay of TDD. We provide a spectral explanation for this behavior by examining the energy gap structure of the Hamiltonian. The results demonstrate how the competition between different types of spin–orbit couplings—antisymmetric DM, symmetric KSEA, and the new in-plane anisotropy <span>(delta )</span>—can be used to control the robustness of quantum correlations against temperature fluctuations.

First, the electronic structure of the pristine SiC nanotube was analyzed, revealing a direct band gap of approximately 1.67 eV, confirming its intrinsic semiconducting character with a non-magnetic ground state. Subsequently, the substitutional doping of Fe at the Si site was introduced to explore the modification of electronic and magnetic properties. The calculated band structure demonstrates that Fe incorporation significantly reduces the band gap to approximately 0.37 eV, indicating strong impurity-induced electronic states within the band gap region. The spin-polarized density of states reveals a pronounced asymmetry between spin-up and spin-down channels, confirming the emergence of magnetism in the doped nanotube. Orbital-projected density of states analysis indicates that the magnetic behavior mainly originates from the partially filled Fe-3d orbitals, which strongly hybridize with the p orbitals of neighboring Si and C atoms. Mulliken population analysis shows that the Fe dopant carries a dominant magnetic moment of 3.14 µ_B, while smaller induced magnetic moments appear on surrounding atoms, leading to a total magnetic moment of 4.005 µ_B for the supercell.
