WebAbstract. Although the natural remanent magnetization of terrestrial igneous rock is often due to multidomain grains of magnetite or titanomagnetite, it is not certain what controls … WebSažetak. The magnetic hysteresis of Fe77.5B22.5 amorphous ribbon has been studied by the induction method. The results for coercive field (Hc), maximum magnetization (Mm) and remanent magnetization (Mr) are explained by the twofold domain structure of amorphous alloys in form of ribbons.
WebIn addition, atomic force microscopy (AFM) was employed for the topographic imaging and force response measurement of the adhesion layer. These results presented that lamellae of phospholipid bilayers were aligned parallel to a surface of a bare Si substrate, whereas a fragile layer of unoriented phospholipid bilayers was formed on a N H 2 WebFeb 1, 1996 · Here we present the remanent coercive force Hcr of grown magnetite grains between 0.09 /~m and 6 mm to obtain a complete set of hysteresis parameters (/-/~, Mrs, …

Coercivity is usually measured in oersted or ampere/meter units and is denoted HC. An analogous property in … See more Coercivity in a ferromagnetic material is the intensity of the applied magnetic field (H field) required to demagnetize that material, after the magnetization of the sample has been driven to saturation by a strong field. This … See more Typically the coercivity of a magnetic material is determined by measurement of the magnetic hysteresis loop, also called the magnetization curve, as illustrated in the figure above. … See more As with any hysteretic process, the area inside the magnetization curve during one cycle represents the work that is performed on the material by the external field in reversing the magnetization, and is dissipated as heat. Common dissipative processes in … See more At the coercive field, the vector component of the magnetization of a ferromagnet measured along the applied field direction is zero.
