a Structures of 2H-TaS2, Cr1/4TaS2, and Cr1/3TaS2, with 1 × 1, 2 × 2, and \(\sqrt{3}\times \sqrt{3}\) unit cells. b Raman spectra of Cr1/4TaS2, Cr1/3TaS2, and 2H-TaS2, with Cr superlattice phonon modes highlighted. c Selected area electron diffraction of an exfoliated flake of Cr1/4TaS2, with primitive and superlattice reflections indicated. d Virtual dark-field images from four-dimensional scanning transmission electron microscopy (4D-STEM) reconstructed using the intensities of 2 × 2 and \(\sqrt{3}\times \sqrt{3}\) Bragg disks. e 4D-STEM diffraction patterns from the regions indicated in (d). f Field-cooled (FC) and zero-field-cooled (ZFC) DC magnetic susceptibility (χDC) vs. T, measured with a 100 Oe field parallel and perpendicular to c. g Real part of the AC susceptibility (\({\chi }_{{{\rm{AC}}}}^{{\prime} }\)) vs. T, measured with an in-plane AC field of 10 Oe. h Isothermal magnetization (M) vs. μ0H⊥c. i Arrott plot with linear fit to the 96 K trace.
