Abstract

We have synthesized a new organometallic material that is predicted to be multiferroic. Ferroelectric materials can pave a way to exciting new technologies, such as FRAM. Bis(Diisopropylamonium) Cobalt(II) Tetrachloride, BLUE, is grown from beaker solutions containing; molar solution Cobalt(II) Chloride Hexahydrate(237.93g/L), Hydrochloric Acid (HCL), and 48 5th Annual Student Research Symposium Diisopropylamine (DIPA). Its density is 1.309 g/cm3 and melting point is above 130°C. Weak ferroelectric results are shown by Piezo Force Microscopy imaging a process of “reading and writing” domains onto ferroelectrics, while piezoelectric results are point tested with responses of 5-12 nA and qualitative hysteretic results. The Radiant System testing has shown butterfly curves that indicate piezoelectric responses for different samples of blue, and lemon shaped hysteresis curves due to resistance. Further testing is to be conducted on larger crystals and different axes with Atomic Force Microscopy and bulk capacitance testing.
