Abstract : The kinetics of crystal growth on a seed in solutions has been studied for the antiferromagnetic water soluble crystal Cu(CH3000)2H2O I around 1-2C and the rate of growth and dissolution has been investigated for the ferroelectric Rochelle salt crystal NaK C2H4O2(COO)2.4 H2O II around 19 and 24C. The antiferromagnetic Neel point T(N) of I is 7C and the ferroelectric Curie temperature T(c) of II is 24C. The growth of crystals I has been performed also in high magnetic fields up to 142 KOe. Two crystals of I, one outside and the other inside the high magnetic field have been investigated. The Isothermal rate of growth inside the field has been at a temperature about 0.3C higher than outside the field. (Author)
