Article for use in magnetic heat exchange, intermediate article and method for producing an article for use in magnetic heat exchange An article for magnetic heat exchange is produced by heat treating an intermediate article comprising, in total, elements in amounts capable of providing at least one magnetocalorically active LaFe13-based phase and less than 5 Vol % impurities, wherein the intermediate article comprises a permanent magnet. The intermediate article is worked by removing at least one portion of the intermediate article. The intermediate article is then heat treated to produce a final product comprising at least one magnetocalorically active LaFe13-based phase.
