    Magnetic Permeability - an overview | ScienceDirect Topics

    The saturation in IRM acquisition curves is mainly influenced by the concentration of magnetite-type and hematite-type minerals. Magnetite and maghemite are magnetite-type minerals and have low coercivity, which means that they are magnetically soft and reach saturation in fields up to 300 mT, resulting in a flat curve at higher fields.

    The role of magnetic interaction in TRM acquisition is also important at higher concentrations of magnetite ( C ≳ 0.1%), where the value of TRM/SIRM increases with decreasing concentration. It is only for concentrations of C ≲ 0.1% that the value of TRM/SIRM is fairly constant and interactions among magnetite grains seem to be ignored.
