Abstract

The two-dimensional oxalate-based magnet {[N(C₄H₉) ₄][NiCr(ox)₃]} _n (ox = C₂ O₄^2-) was studied in its two enantiomeric forms. The X-ray Magnetic Circular Dichroism (XMCD) was measured at 11 K, e.g. under the Curie temperature of the compound (16 K). The XMCD signal is identical for the two enantiomers. The XMCD spectra at the chromium and nickel K-edges confirm the ferromagnetic coupling between the metal ions. The remnant local magnetic moments on the Cr and Ni ions have been clearly evidenced, analysed and compared to the total remnant magnetisation measured at 11 K by conventional magnetometry.
