Abstract
Precise linear birefringence measurements were performed for two isomorphic crystals: (CH3)2NH2H2AsO4 and (CH3)2NH2H2PO4. Anomalous cusp-like maxima of linear birefringence increments, i.e. changes of birefringence caused at the phase transition, were revealed in the ferroelectric phase. Dilatometric studies confirmed that these increments can be connected with similar anomalies of spontaneous strain.
