Abstract: According to various aspects of the instant disclosure, a rapidly-sedimenting magnetic particle can include a core or inner layer. The core or inner layer can include a ferrimagnetic material and have at least one of a maximum field strength ranging from about 20 emu/g to about 250 emu/g, and a remanence ranging from about 0 cmu/g to about 20 emu/g. The rapidly-sedimenting magnetic particle can further include a coating layer overlaying at least a portion of the core or inner layer. The particle can further include an outer coating layer overlaying at least a portion of the core coating.
