Remanence magnetization isothermal

FIGURE 22 The time decay of the isothermal remanent magnetizations Im of H0B22C2N and ErB22C2N at 5 and 2 K, respectively. The lines depict the stretched exponential fit ... 

Isothermal remanent magnetization (IRM) The magnetization that remains in a sample after the sample has been removed from an applied magnetic field. 

Saturation isothermal remanent magnetization (SIRM) The maximum remanence that can be attained in a sample after exposure to a strong magnetic field, generally 1 T.

To further confirm the nature of magnetic interactions, the isothermal remanence magnetization (IRM) curve Mr(H) and DC demagnetization (DCD) curve A1d(H), both normalized to the saturation remanence, have been plotted at 20K. From these curves, a Henkel plot has been obtained (Fig. 2l.l0a). In a perfectly noninteracting system of single-domain particles, the slope of the Henkel plot should be —2 and the experimental points would lie on the upper limit of this plot [37], The types of interactions are characterized by means of 8M plots (Fig. 21. lOb) obtained using the following relation ...

FC), remanence (TRM measured after FC, IRM measured after ZFC) and slow (non-exponential) relaxation exist after magnetic perturbation (TRM denotes the thermoremanent magnetization, and IRM the isothermal remanent magnetization).

In the case of dc applied field, three different primary remanent magnetization curves can be measured. They are thermoremanent magnetization (TRM), isothermal remanent magnetization (IRM), and dc demagnetization (DcD) curves. ...
