摘要
Chromium thio-phosphate, CrPS4, has a layered structure based on hexagonally close packed sulfur layers. Magnetic susceptibility measurements indicated an antiferromagnetic ordering perpendicular to the C axis and the presence of trivalent chromium in the paramagnetic region. Optical transmission spectra showed the fundamental absorption edge to occur at 2.4 eV. Using n-butyl lithium techniques, it was found that CrPS4 can readily accomodate lithium. This insertion is not allowed by any parameter change in the host structure nor reduction of the Cr3+ magnetic moment. Lithium NMR measurements gave a rather high (0.31 eV) energy of activation for lithium movement and use of CrPS4 as a cathode against a lithium anode showed a sharp drop in potential.
