Abstract

The patterns of the magnetic structure of the magnetic fluid thin film under tilted magnetic fields were taken to investigate the behavior of magnetic structures. The tilted angle θ is the angle between the direction of applied magnetic field and the normal line of the film. In our previous work, a nearly perfect ordered hexagonal structure in magnetic fluid thin film was obtained when a perpendicular magnetic field (θ = 0) was applied. By increasing θ, each column in the hexagonal structure gradually tilted to reveal a lattice of segments instead of dots on the pattern with an unchanged lattice distance d. As θ exceeding a critical value θc, these segments began to form longer periodic chains with an abrupt increasing of d. Hence, a transition from the magnetic hexagonal structure to a periodic chain structure at θc existed for magnetic fluid thin film in which the θc decreases exponentially as the sweeping rate increases.
