Charge Order Breaks Magnetic Symmetry in Molecular Quantum Spin Chains
Figure 7
Temperature dependence of the normalized mosaicity of and determined from the width of the X-ray spots (after [54]). When the temperature drops below 200 K, the mosaicity of increases dramatically approaching a maximum at the charge-order temperature K. For comparison the behavior of is also presented where only a small increase is observed. Note, in the case of the phase transition happens only at K.
