Abstract A kagomé antiferromagnet presents an ideal construct for studying the unusual physics that result from the placement of magnetically frustrated spins on a low‐dimensional lattice. Jarosites are the prototype for a spin‐frustrated magnetic structure, because these materials are composed exclusively of kagomé layers. Notwithstanding, jarosite‐type materials have escaped precise magnetic characterization over the past three decades, because they are notoriously difficult to prepare in pure and single‐crystal forms. These hurdles have been overcome with the development of redox‐based hydrothermal methods. Armed with pure and crystalline materials, several perplexing issues surrounding the magnetic properties of the jarosites have been resolved, yielding a detailed and comprehensive picture of the ground‐state physics of this kagomé lattice.
