Remanent magnetization of fine particles

- We have performed measurements of the decay of a signal recorded on single layer CoCr films using a thin film ring head.. These results are compared with data obtained by

Annealed, unstrained nickel : values of b", calculated form the theory of Stoner and Rhodes. difficult it is to deduce precise values for b’ from results obtained

In figures la and 16 we show the decay of the remanent magnetization and the excess of the intemal energy for the three-dimensional binary Ising spin glass at four temperatures

The problem is analysed in two limiting cases; the case of the random interaction and the fixed value of the spin and the case of the fixed interaction and the random

The bias fields referred to are generally such as t o induce only a low level of magnetization compared with that induced by the subsequent application of the stress, but no

L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des

The irreversible properties of a mictomagnetic alloy are similar to those of a spin glass, (the magnetization measured in the field H after a zero field cooling down to T <

Balthasar (2018) wrote a detailed review of observations, where it is shown that typical values of 3 G km −1 and 0.3 G km −1 are obtained for the vertical and horizontal gradients
