Hierarchical microstructure and magnetic anisotropy of peanut‐shaped colloids promotes a permanent transverse magnetic dipole, leading to rich self‐assembly behavior. Crisscross and planar zigzag chains (see image; scale bar = 2 µm in A and 5 µm in B), as well as a molecular crystal‐type phase with oblique symmetry in 2D are observed.
