Effect of deuteration on the phase transition of pure and Cr3 -doped triglycine selenate TGSe

Results of dielectric studies are reported in triglycine selenate crystals DTGSe, pure and admixtured with chromium ion DTGSe+ Cr³⁺. From these results and observations double hysteresis loops above the Curie temperature, the DTGSe and DTGSe + Cr³⁺ crystals are found to undergo a phase transition of the I-st kind.
