Microstructural Analysis and Magnetic Characterization of Native and Magnetically Modified Montmorillonite and Vermiculite

Table 4

Room temperature (RT≈300 K) and low-temperature (LT≈2 K) magnetic parameters of the original (Mt, Ver) and magnetically modified (MVer, MMt) vermiculite and montmorillonite samples; : magnetization; _r: remanent magnetization; _c: coercivity.
