Abstract

An experimental and theoretical investigation of the behavior of a dipolar ring in a magnetic field perpendicular to its plane was carried out. Experimentally, it was found that when the value of the external magnetic field B falls below a lower critical field Bc1, the dipoles rotate in the ring without any distortion of the ring structure. However, exceeding an upper critical field Bcu caused a sudden breakup of the ring into short chains aligned with the field. The time evolution of the breakup process was clarified via computer simulations.
