Magnetization reversal in magnetic microwires was studied in the presence of external mechanical stress and helical magnetic fields using the magneto-optical Kerr effect. It was found that a combination of tuned magnetic anisotropy and a direct current or pulsed circular magnetic field activated different types of magnetization reversal scenarios. The application of the pulsed magnetic field of 10 ns time duration induced a transient controlling action to switch the magnetic states without activating a domain wall motion. This created a promising method for tuning the giant magneto-impedance effect.

通过脉冲圆形磁场控制玻璃涂层非晶微丝中的可逆磁化开关

在存在外部机械应力和螺旋磁场的情况下，使用磁光克尔效应研究了磁性微丝的磁化反转。发现调谐磁各向异性和直流或脉冲圆形磁场的组合激活了不同类型的磁化反转场景。持续时间为 10 ns 的脉冲磁场的应用引起了瞬态控制作用，以在不激活畴壁运动的情况下切换磁状态。这为调整巨磁阻抗效应创造了一种很有前途的方法。
