摘要：

Large magnetosomes of 40 nm diameter were characterised by altogether four different methods, i.e. DC-magnetometry and magnetorelaxometry as integral tools, and atomic and magnetic force microscopy as microscopic tools. The results suggest that the integral hysteretic behaviour of magnetosomes can be understood as a superposition of their microscopic behaviour, ignoring interaction between the particle moments.
