“…5,31,32 Phase images of On the contrary to the extreme case of pure N-FM state of Figure 1(c), phase variations can still be visible in some β domains in Figure 2 during the transition, especially at low temperatures. The corresponding magnetic induction in the positions of β domains come from the leakage field between two adjacent FM α domains.…”

“…For the studied sample, some defects, e.g. the grain boundaries and possibly edge dislocations, 31 are visible in the amplitude image of Figure 1 In addition to the defect influence, Figures 2 and 3 also demonstrate significant surface and interface effects. The magnetic contrasts corresponding to α Type-I domains always initially appear in a well defined position at about 75 nm from the interface as previously mentioned, grow laterally along the x direction, and then gradually expand in the y direction towards the surface and interface.…”

“…To give direct evidence for the assignment of the ridges to the ferromagnetic α-phase, we employed magnetic force microscopy (MFM) [22]. By varying the working distance of the cantilever, images with topographical and magnetic contrast of the same area are obtained.…”

“…At RT the MnAs film is compressively strained along the MnAs[1120] direction and tensile strained along the MnAs[0001] direction. This leads to a self-organized stripe pattern with alternating ferromagnetic α-MnAs (ridges) and paramagnetic β-MnAs stripes (grooves), oriented along the MnAs[0001] direction [8][9][10][11]. The surface can be characterized by the period of the stripe pattern d and the width of the ferromagnetic stripes L. …”
