Abstract: A switchable magnetic device comprising a first ferromagnetic material or layer comprising or consisting of a first rare earth nitride alloy, the first rare earth nitride alloy including at least two lanthanide species; a second ferromagnetic material or layer comprising or consisting of a second rare earth nitride alloy, the second rare earth nitride alloy including at least two lanthanide species; a blocking material or layer located between the first and second ferromagnetic materials or layers.

Abstract: A system for asset tracking, comprising a universally accessible property tracking database. The database is based on an organization-property-individual model, and uses automatic close-match searching to match lost and found items. Any type of property can be reported found, registered, and reported lost, and recovered property can be returned to its owner. Embodiments of the system include on-line access that allows a user or organization to register an item, based upon the item's characteristics or an affixed label code. If the item is lost due to accident, theft, or damage, the system can be used to register the lost item and to generate reports and insurance claim information. A user who finds an item may register the item as a found item. When a match is found between a registered lost and registered found item the system may be used to return the item to the proper owner.
