纳米坡莫合金三角形的六重组态各向异性和磁反转
Six-fold configurational anisotropy and magnetic reversal in nanoscale Permalloy triangles
摘要：
在坡莫合金三角形中研究了六重构型各向异性，其中形状对称顺序产生两个能量非简并的自旋微磁构型，即所谓的“Y”和“屈曲”状态。一个十二点开关星形线测量使用磁光实验，并成功地再现数值，与不同的极性象限确定为特定的磁过渡，从而给出了一个全面的看法，在这些结构中的磁反转。详细的分析强调了在模拟中包括结构的物理舍入以解释Y状态的不稳定性的必要性。
英文摘要：
Six-fold configurational anisotropy was studied in Permalloy triangles, in which the shape symmetry order yields two energetically non-degenerate micromagnetic configurations of the spins, the so-called "Y" and "buckle" states. A twelve pointed switching astroid was measured using magneto-optical experiments and successfully reproduced numerically, with different polar quadrants identified as specific magnetic transitions, thereby giving a comprehensive view of the magnetic reversal in these structures. A detailed analysis highlighted the necessity to include the physical rounding of the structures in the simulations to account for the instability of the Y state.
