Remanence or remanent magnetization or residual magnetism is the magnetization left behind in a ferromagnetic material (such as iron) after an external...

Data remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue...

paleomagnetism to understand how rocks record the Earth's magnetic field. This remanence is carried by minerals, particularly certain strongly magnetic minerals...

history dependence is the basis of memory in a hard disk drive and the remanence that retains a record of the Earth's magnetic field magnitude in the past...

the magnetization is offset from the origin by an amount called the remanence. If the H-M relationship is plotted for all strengths of applied magnetic...

field inside the material) to zero. The remanence coercivity, HCr, is the H field required to reduce the remanence to zero, meaning that when the H field...

largest switching field. The other two types of remanence involve demagnetizing a saturation isothermal remanence (SIRM), so in normalized units they start...

commonly called magnetic remanence or remanent magnetization. Proper degaussing will ensure there is insufficient magnetic remanence to reconstruct the data...

since been extended to apply to computer files and the problem of data remanence. In the context of government documents, redaction (also called sanitization)...

quickly when power is removed. However, DRAM does exhibit limited data remanence. DRAM typically takes the form of an integrated circuit chip, which can...
