Abstract
The results of a detailed comparative bulk magnetization study of nanocrystalline (average crystallite size ≃25 nm) and polycrystalline samples of Ni3Al reported here clearly demonstrate that unlike crystalline Ni3Al, which is a well-known weak itinerant-electron ferromagnet, no long-range ferromagnetic order exists in the nanocrystalline counterpart at any temperature >~5 K. Instead, nanocrystalline Ni3Al exhibits exchange-enhanced Pauli spin paramagnetism.
