Optical manipulation of stripe domains and magnetic bubbles. (A) A pump laser spot (1,300 nm, 160 nJ) exerts an attractive force to the stripe domains as observed by Faraday microscopy with Xe lamp illumination. Bottom row shows the difference of the successive images illustrating the motion of the stripe domains upon the displacement of the laser spot (orange arrows). (B) Optically controlled elongation and bending of the stripe domain. The laser spot (emphasized with a red circle) was scanned laterally in the images, in which the initial motion of the stripe domain is indicated by a dotted arrow for clarity. Surrounding stripe domains also changed their lengths due to the dipole interaction. (C) Magnetic bubble domains are driven by the laser spot. The smaller bubbles (lower panels) can be more easily manipulated compared with the larger ones (upper panels). Corresponding movies can be found in Supporting Information.
