3 Terms and definitions

The following terms and definitions apply to this document: The ISO and IEC terminology databases are accessed via: ---ISO :http://www:iso:org/obp 3:1 AC susceptibilityACsusceptibility The complex ratio of the dynamic magnetization to the applied magnetic field: Note 1: The dynamic magnetization intensity is M = M0e(i2πft-ϕ), and the external magnetic field is H = H0ei2πft: AC magnetic susceptibility χ = M/H is divided into in-phase components (real part) And the non-phase component (imaginary part): χ =χ'-iχ″: Note 2: Depending on the type of magnetization used, the AC susceptibility of the material is related to the volume, mass or quantity of the material: AC volume magnetic susceptibility: χV= M0V H0 cosφ-i M0V H0 sinφ AC mass magnetic susceptibility: χm= M0m H0 cosφ-i M0m H0 sinφ AC molar susceptibility: χn= M0n H0 cosφ-i M0n H0 sinφ Note 3: AC magnetic susceptibility depends on the excitation field frequency and temperature and should also be noted: Note 4: The amplitude of the excitation field should be small enough to ensure a linear relationship between the amplitude of the dynamic magnetization and the amplitude of the applied AC field: 3:2 agglomerate An aggregate of weakly or moderately bound particles has a surface area similar to the sum of the surface areas of individual particles: Note 1: The forces holding the agglomerates together are weak forces, such as van der Waals forces or simple physical entanglement: Note 2: Agglomerates are also called secondary particles, while source particles are called primary particles: Note 3: The primary particles themselves can be composite particles with magnetic and non-magnetic parts: [Source: ISO /T S80004-2:2015,3:4] ......
