Simulated transition path between the high- and the low-moment states of a double-stranded chain of 11+10 equidimensional magnetosomes

Assumptions: 50 nm spherical magnetosomes with a saturation magnetization of 480 kA/m (magnetite) separated by 5 nm gaps, divided in two staggered strands of 11 and 10 crystals, respectively.Initial state: SD-like state with same-polarity.strandsFinal state: flux-closure state with opposed-polarity strands.CSV data structure with magnetosomes numbered from 1 to 21 starting from one chain extremity of strand 1 and continuing with the same side in strand 2. Magnetic moment directions are given in spherical coordinates with respect to the chain axis. Column 1: total energy normalized by kT, with T = 293 K. Columns 2-22: polar angles of the magnetic moments of individual magnetosomes (theta01, ..., theta21). Columns 23-43: azimuthal angles of the magnetic moments of individual magnetosomes (phi01, ..., phi21).
