论文摘要
我们报告LA $ _ {1-X} $ sr $ _x $ mno $ _3 $ $ x for $ x = $ x = $ 0.125的la $ _ {1-x} $ _ $ _ {1-x} $ _ $ _x $ _x $ _3 $的磁纹理形成;这些纹理是磁性气泡，磁条带域和强制FM状态。原位Lorentz显微镜（LM）观察结果表明，磁性气泡存在于FM绝缘阶段，伴随着电荷$/$/$轨道订购的形成（CO $/$ OO）。此外，稳定的磁性气泡仍然存在于CO $/$ OO（$ T_ {CO} = $ 155 K）和FM（$ T_C = $ 190 K）过渡温度之间的中等温度区域中。这些磁性气泡被认为起源于磁晶的各向异性和FM相中的偶极 - 偶极相互作用。基于原位LM观测，构建了磁场 - 温度相图，构建了磁场 - 温度相图，在LA $ _ {0.875} $ _ {0.875} $ sr $ _ {0.125} $ mno $ mno $ $ $ $ $ _ {3} $ _ {3} $ _ {3} $ _ {3} $ _ {3} $ _ {3}的FM期中显示了磁性气泡的稳定区域。
We report formation of magnetic textures in the ferromagnetic (FM) phase of La$_{1-x}$Sr$_x$MnO$_3$ for $x =$ 0.125; these textures are magnetic bubbles, magnetic stripe domains, and forced FM states. In situ Lorentz microscopy (LM) observations show that magnetic bubbles exist in the FM insulating phase accompanying the formation of the charge$/$orbital ordering (CO$/$OO). Furthermore, stable magnetic bubbles still exist in an intermediate temperature region between the CO$/$OO ($T_{CO} =$ 155 K) and FM ($T_c =$ 190 K) transition temperatures. These magnetic bubbles are believed to originate from the magnetocrystalline anisotropy and the dipole-dipole interaction in the FM phase. Based on in situ LM observations as a function of both temperature and the strength of the external magnetic field applied, a magnetic field-temperature phase diagram is constructed, exhibiting the stabilizing regions of the magnetic bubbles in the FM phase of La$_{0.875}$Sr$_{0.125}$MnO$_{3}$.
