(a) The sketch of the curved film. The size of the film is fixed at length of 400 nm, width of 250 nm, and thickness of 10 nm. Then, it is curved to a circularly curved film with a fixed radius R, where R varies from 40 nm to infinity. (b) The hysteresis loops for the curved films with R = 60, 150 and inf, respectively. (c) The susceptibility at Hz = 0 as a function of R.
