Application In Synthesis of Cupric bromide The article mentions the following:
Type-II multiferroic materials, in which ferroelec. polarization is induced by inversion nonsym. magnetic order, promise new and highly efficient multifunctional applications based on the mutual control of magnetic and elec. properties. Although this phenomenon has to date been limited to low temperatures, here we report a giant pressure dependence of the multiferroic critical temperature in CuBr2. At 4.5 GPa, TC is enhanced from 73.5 to 162 K, to our knowledge the highest value yet reported for a nonoxide type-II multiferroic. This growth shows no sign of saturating and the dielec. loss remains small under these high pressures. We establish the structure under pressure and demonstrate a 60% increase in the two-magnon Raman energy scale up to 3.6 GPa. First-principles structural and magnetic energy calculations provide a quant. explanation in terms of dramatically pressure-enhanced interactions between CuBr2 chains. These large, pressure-tuned magnetic interactions motivate structural control in cuprous halides as a route to applied high-temperature multiferroicity. The experimental part of the paper was very detailed, including the reaction process of Cupric bromide(cas: 7789-45-9Application In Synthesis of Cupric bromide)
Some reported applications of Cupric bromide(cas: 7789-45-9) are: catalyst in cross coupling reactions; co-catalyst in Sonogashira coupling; lewis acid in enantioselective addition of alkynes.Application In Synthesis of Cupric bromide
