求翻译：在较小的磁场作用下，磁矩方向与外加磁场方向一致或接近的磁畴体积增大，而磁矩方向与外加磁场方向相反的磁畴体积减小，畴壁发生位移是什么意思？

Smaller magnetic field, the magnetic moment direction of the magnetic field in the same direction or close to the magnetic domain volume increases, while the magnetic moment direction of the applied magnetic field in the opposite direction of the magnetic domain volume decreases, the domain wall dis

In a small magnetic field, the magnetic moment with Direction plus a magnetic field direction close to the magnetic field or volume increases, the magnetic moment with plus magnetic field direction opposite magnetic fields decrease volume, wall areas shift

Under the small magnetic field function, the magnetic moment direction consistent or the close magnetic domain volume increases with the sur- magnetic field direction, but the magnetic moment direction and the sur- magnetic field direction opposite magnetic domain volume reduces, the domain wall has

Under the small magnetic field, magnetic moment and the magnetic field line, or close to the magnetic domain size increases, and the magnetic moment and the magnetic field in the opposite direction of the volume decrease of magnetic domain, domain wall displacement
