Magnetic remanence

The first application has been fully developed and is performed in a routine service Turbine disks are tested for extremely small iron inclusions. The physical principal is to measure their magnetic remanence. [Pg.991]

Biogenic magnetite may persist once the organism that produced it has died and may, therefore, contribute to the natural magnetic remanence of sediments (Stolz et al., 1986). The discovery in a calcareous Martian ( ) meteorite found in Antarctica, of magnetite crystals with properties very similar to these biogenic magnetites, sup-... [Pg.485]

In the magnetic remanence experiments the samples are exposed to a combination of much stronger specific magnetic fields than those that are applied in magnetic susceptibility analyses. After exposnre to each successive magnetic field, the remanent magnetisation is measured. When the magnetisation is measnred out of the field , only substances that are... [Pg.231]

Magnetic and mechanical properties were measured by [1932Koe2]. Brinell hardness, eoereivity and magnetic remanence were measured. [1985Koz] measured the microhardness of modulated sfructures in die metastable spinodal alloys. Physical property investigations are listed in Table 5. [Pg.651]

According to Figure 15.11(a), the hysteresis curve for ferrite nanopowders at room temperature showed that the particles are ferrimagnetic above the blocking temperature of 50 The hysteresis loop parameters, like saturation magnetization (Ms), coercivity field Hq), magnetic remanence (Mr) and an...

Magnetic remanence, especially the squareness, provides information about coupling mechanisms between metal nanostmctures (Stoner and Wohlfarth 1948). Ferromagnetic stmctures with a random distribution of orientations offer a squareness of 0.5. In comparison stmctures with the easy axis aligned parallel to the applied magnetic field exhibit a squareness of 1 whereas with the easy axis perpendicular to the magnetic field a value of 0 (Coey 2009). A decrease of the squareness... [Pg.196]
