This dataset contains the experimental and computational data associated with the article “Confinement-tuned magnetic competition and spin-asymmetric transport in quasi-one-dimensional NiCl₂ confined within carbon nanotubes”, published in Carbon.
The dataset includes high-resolution STEM/EDS characterization data of NiCl₂ encapsulated within single-walled carbon nanotubes (SWCNTs), along with supporting experimental observations of structural configurations and filling behavior. In addition, it provides results from spin-polarized density functional theory (DFT+U) calculations, including electronic structure data such as projected density of states (PDOS), band structures, charge density distributions, COHP analysis, and transport-related quantities derived from velocity-weighted metrics and BoltzTraP2 simulations.
The data support the investigation of confinement-induced modifications in magnetic ordering and spin-dependent transport properties of quasi-one-dimensional NiCl₂ fragments inside carbon nanotubes, including the competition between ferromagnetic and antiferromagnetic states and the emergence of spin-asymmetric transport behavior.
All figures and tables presented in the publication are included in reproducible formats, together with underlying numerical data where applicable. This dataset is provided to ensure transparency, reproducibility, and further reuse in studies of low-dimensional magnetism, confined halide systems, and carbon nanotube-based hybrid materials.
