Enhanced Polarization in Tadpole-shaped (ni, Al)/aln Nanoparticles and Microwave Absorption at High Frequencies


Tadpole-shaped (Ni, Al)/AlN nanoparticles were synthesized via evaporating Ni-Al alloy in a mixed atmosphere of N2 and H2. As a counterpart, the spherical-shaped (Ni, Al)/Al2O3 nanoparticles were also prepared from the same target alloy while in a mixture of Ar and H2. The electromagnetic parameters of as-made nanoparticles/paraffin composites were then… (More)
