Two Triangles
FePt / 330 nm
Magnetostatic interactions between triangles are very weak (the same MHL for two single crystal triangles head-to-head compared with MHL loop of a single triangle):
Two single crystals head-to-head
Several crystallites, four possible orientations (all 4 diagonals of the cube)
Each color means one e.a. orientation
