Electrosynthesis of crystalline rare-earth chromates of the formula Ln CrjOj 7HjO (Ln = La, Pr, Nd) has been carried out by the cathodic reduction of an Ln(N03)3 solution containing K Cr O [15]. Coatings of these materials on heat treatment (750°C, lOmin) yield adherent LnCrOj coatings. Ferromagnetic coatings...
