Modified TGS single crystals have been grown by doping with Cobalt (II) Phosphate in ferroelectric phase. The effects of different amounts of doping entities on the growth habit and P ‐ E hysteresis loop have been investigated. The experimental results show that while the spontaneous polarization P s measured on variously doped crystals remains virtually unchanged, the coercive field values differ in dependence on the growth conditions and grown pyramidal features. The highest values of the coercive field E c have been found to fall in the interval 800‐900 V/cm.
