Based on extensive Langevin Dynamics simulations we investigate the structural properties of a two-dimensional ensemble of magnetic rods with a peapod-like morphology, i.e, rods consisting of aligned single dipolar beads. Self-assembled configurations are studied for different directions of the dipole with respect to the rod axis. We found that with increasing misalignment of the dipole from the rod axis, the smaller the packing fraction at which the percolation transition is found. For the same density, the system exhibits different aggregation states for different misalignment. We also study the stability of the percolated structures with respect to temperature, which is found to be affected by the microstructure of the assembly of rods.
基于广泛的朗之万动力学模拟，我们研究了具有豆荚状形态的二维磁棒集合体的结构性质，即由排列整齐的单偶极子珠组成的棒。我们研究了不同偶极方向相对于棒轴的自组装构型。我们发现，随着偶极相对于棒轴的失配增加，发现渗流转变时的填充率越小。对于相同的密度，系统对于不同的失配表现出不同的聚集状态。我们还研究了渗流结构对温度的稳定性，发现它受到棒集合体的微观结构的影响。
