摘要：

A pair of parallel uniaxial particles with dipole-dipole coupling has, for bond angles β=0 and π/2, up to four locally stable configurations: ↑↑, ↑↓, ↓↑, and ↓↓. Assuming thermal relaxation via coherent rotation and a periodic driving field we solve a master equation for the occupation probabilities of these states and find the coercivity and switching field distribution of the ensemble of coupled particles. For either value of the bond angle we compare numerical solutions of the master equation with approximate expressions based on extremal analysis and find good agreement between the two.
