Exploring the effect of volumic fraction on binary ferrofluids with RIXS-MCD spectroscopy

We propose to study the effect of assembling phenomena in bimagnetic spinel-ferrite ferrofluids combing of soft and hard ferrimagnets on their magnetic properties. These bimagnetic ferrofluids offer a unique possibility to manipulate the magnetic properties of the individual particles due to the formation of self-assemblies as a result of dipole-dipole interactions. Our goal is to determine the effect of self- and field-assembly formation on the magnetic properties of CoFe2O4- MnFe2O4 binary ferrofluids using the element-selective 1s2p RIXS-MCD at ID26 beamline. These results will pave the way towards building a comprehensive picture of assembling phenomena in ferrofluids and the design of future magneto-intelligent fluids.
