论文摘要
我们通过Lorentz显微镜检查了M型六角形中磁泡的形成机理。当磁场垂直应用于薄薄的Bafe $ _ {12-x-x-0.05} $ sc $ sc $ _x $ _x $ _x $ _g $ _ {0.05} $ o $ $ $ $ _ {19} $（$ x = 1.6 $），bloch线，bloch bloch，被确定为弹药的频率，并绘制了磁性的范围。 Bloch线。 BLOCH线的数量随BAFE $ _ {12-x-0.05} $ sc $ _x $ _x $ mg $ _ {0.05} $ o $ $ $ _ {19} $增加而增加，这可能是因为磁动率减少。洛伦兹的显微镜观察表明，具有高磁静态能量的Bloch线可能在磁性气泡的形成中起重要作用。
We examined the formation mechanisms of magnetic bubbles in an M-type hexaferrite via Lorentz microscopy. When magnetic fields were perpendicularly applied to a thin sample of BaFe$_{12-x-0.05}$Sc$_x$Mg$_{0.05}$O$_{19}$ ($x = 1.6$), Bloch lines, which were identified as reversals of domain-wall chirality, appeared, and magnetic bubbles were formed when the magnetic stripes were pinched off at these Bloch lines. The number of Bloch lines increased with the amount of Sc in BaFe$_{12-x-0.05}$Sc$_x$Mg$_{0.05}$O$_{19}$ probably because of the reduction in magnetic anisotropy. A Lorentz microscopic observation revealed that Bloch lines with high magnetostatic energy may play an important role in the formation of magnetic bubbles.
