Extended Data Fig. 2: Scanning electron micrographs of arrays of left-handed (LH) and right-handed (RH) artificial chiral magnets (ACMs).
From: Geometry-induced spin chirality in a non-chiral ferromagnet at zero field
The SEM images were acquired at a 30° tilt with respect to the substrate normal. Each array unit comprises a suspended ACM supported by two vertical chiral tubes, enabling top-side optical access. The LH-ACM and RH-ACM arrays were fabricated on the same substrate and received identical Ni coatings in the same ALD run. Geometric parameters (pitch, height, and tube diameter) are nominally the same; only the handedness differs.
