Simulated transition path between the high- and the low-moment states of a circular ring made of 20 equidimensional magnetosomes

Assumptions: 50 nm spherical magnetosomes with a saturation magnetization of 480 kA/m (magnetite) separated by 5 nm gaps.<br>Initial state: two equal, tangentially magnetized domains.<br>Final state: zero-moment flux closure.<br>CSV data structure with magnetosomes numbered from 1 to 20. Magnetic moment directions are given in spherical coordinates with respect to the ring circumference. Column 1: total energy normalized by kT, with T = 293 K. Columns 2-21: polar angles of the magnetic moments of individual magnetosomes (theta01, ..., theta20). Columns 22-41: azimuthal angles of the magnetic moments of individual magnetosomes (phi01, ..., phi20).
