Distribution of magnetization in granular samples

Distribution of magnetization in granular samples

Field distributions in granular spherical samples are discussed analytically. It is shown that (i) all grains in the bulk of the sample are exposed to essentially the applied field, and (ii) grains on the surface of the sample see both smaller and higher fields depending on whether they are near the...

Zusammenfassung:Field distributions in granular spherical samples are discussed analytically. It is shown that (i) all grains in the bulk of the sample are exposed to essentially the applied field, and (ii) grains on the surface of the sample see both smaller and higher fields depending on whether they are near the poles or near the equator of the sample.
