Fig. 3. Reversal of magnetic field in the case of d/P = 1.74.

Fig. 3

(A and B) The POM images show the homogeneous magneto-optic response. Schematics below the images show the calculated corresponding director and magnetic field configurations. Every configuration is represented from two side views: (A) U > Ut(B) and (B) UUt(B). Here, two resulting TICs were observed: the pTIC2 (the second image and the region outside the lines in the third image) and the reversed pTIC (within the lines in the third image). (C) Evolution of structures from pTIC2 outside and reversed pTIC within the lines after B is turned off. (D) Response of the sample on the reversal of B at magnitudes around Bt and U = 0. The third image shows the stable structure that evolves continuously from monodomain pTIC2 at B = 0.
