Effect of Magnetostatic Interaction on the Single Domain Wall Propagation in Magnetic Microwires

We propose a novel method for effective control of the single DW propagation in a specially designed array consisting of two magnetic microwires by the stray field from magnetically softer microwires. We have experimentally demonstrated that the DW velocity of magnetically harder Fe-rich microwire in such linear array is affected by the stray field of magnetically softer Co-rich microwire. Additionally, the domain wall can be braked in the Fe-rich microwire by the stray field produced by Co-rich microwire in such linear array. Observed effect of magnetostatic interaction depends on position of Co-rich microwire in such linear array.
