摘要

•Multi-dimensional Ni@C-CoNi with 0D CoNi alloy and 1D Ni@C were synthesized.•The multi-layer heterogeneous interfaces trigger strong interfacial polarization.•Inner 1D Ni interacts with outer 0D CoNi alloy to induce magnetic coupling.•An optimal RL value of -51.4 dB and bandwidth of 4.6 GHz were achieved.
