Abstract
Optical microscope observations and linear birefringence measurements were performed to obtain more information on the phase transitions and phases pr operties of the N(CH3)(4)FeCl4 single crystal. At least four phase transiti ons of first order were detected (at 385 K, 303 K, 294 K and 265 K on cooli ng), some of them of very low kinetics and large thermal hysteresis. The ph ase above 386 K was found as an isotropic one.
