摘要：There is a considerable amount of work that shows the biomagnetism of organic components without ferromagnetic components at the molecular level,but it is of great challenge to cover the giant gap of biomagnetism between their experimental and theoretical results.Here we show that the diamagnetism of aromatic peptides is greatly enhanced for about 11 times by self-assembling,reaching two orders of magnitude higher than the mass susceptibility of pure water.The self-assembly of aromatic rings in the peptide molecules plays the key role in such a strong diamagnetism.
