Column 1 (a–c): incident intensity distributions of the BG beams in the xy plane. (d–l) Light-induced magnetization distributions of tightly focusing CPBG beams with different m orders. (d–f) m=0, (g–i) m=1, (j–l) m=2. Column 2 (d, g and j) distributions of the longitudinal component Mz, column 3 (c, h and k) the azimuthal component Mφ, and column 4 (f, i and l) the total magnetization M in the rz plane. The dimension of the xy plane is 4 × 4 mm, and that of the rz plane is 2λ × 2λ. Column 4 (m–o) represents the cross-sectional plots of the magnetization distributions for various orders. (m) m=0, (n) m=1, (o) m=2. The black, red and green curves denote M, Mφ and Mz along the r axis, and the blue curve represents M along the z axis.
