Maghemization
WebOne of the most common weathering processes is maghemization, which is the oxidation of (titano)magnetite at ambient temperatures, i.e., the slow oxidation of (titano)magnetite to … WebOct 9, 2024 · Magnetization of a ferro- or ferrimagnet vs. applied magnetic field H. Starting at the origin, the upward curve is the initial magnetization curve. The downward curve after saturation, along with the lower return curve, form the main loop. The intercepts Hc and Br are the coercivity and remanent magnetization.
