| Abstract: | Measurements have been made on specimens in which grains of magnetite of diameter 200 μm were dispersed and immobilized. The results obtained for magnetization and demagnetization by isothermal, anhysteretic and heating procedures are given, and discussed in terms of a model which assumes that the grains comprise a central core of magnetic domains separated by 180° domain walls enclosed in a thin surface layer comprised of pseudo single-domain-like domains. |
