Abstract
Ferrite particles having a plurality of distinct Curie temperatures are encapsulated within a polymer matrix to provide tagging material especially useful in identifying explosive materials even after detonation. In one embodiment, phosphor is dispersed within the polymer matrix to facilitate collection of tag particles following detonation. The tags are also usable in tagging other articles, especially where harsh environmental conditions are likely to be encountered.
