Extended Data Figure 7: Positioning a target flake.
From: Discovery of intrinsic ferromagnetism in two-dimensional van der Waals crystals
a, The pre-defined patterns of metal pads. b, A scanned map of the reflectance of the specimen. The colour represents the reflected light intensity. The reflectance of metal pads can vary because some pads were peeled off during the exfoliation process. c, A smaller-size scanning. The units of the numbers on the axes in b and c are millimetres.
