Mixed Halide Chemistry

Caption

Chromium chloride and chromium bromide were known in the past as transition-metal halides with in-plane and out-of-plane magnetization. Boston College researchers have discovered a way of making mixed halides with all the composition between these two parameters. The result of this "mixed halide chemistry" was a combination of chromium chloride and bromide where adjustments to the ratio of chlorine to bromine can be varied continuously. The team observed a continuous change of magnetization from in-plane to out-of-plane as it adjusted the ratio. Small crystals of chromium mixed halides with different chlorine to bromine ratios are shown in the image.
