The Interest packet is then forwarded to a next hop in accordance with the forwarding information.

The magnetic tunnel junction device comprises a first reference magnetic material layer, a tunnel barrier material layer, a free magnetic material layer between the first reference magnetic material layer and the tunnel barrier material layer, and a second reference magnetic material layer disposed on an opposite side of the tunnel barrier material layer from the free magnetic material layer, in which the second reference magnetic material layer is anti-magnetically exchanged coupled with the first reference magnetic material layer. A shift field Hshift experienced by the free magnetic material layer is substantially canceled by the anti-magnetic exchange coupling between the first reference magnetic material layer and the second reference magnetic material layer.
Magnetic memory device having cobalt-iron-beryllium magnetic layers
Example embodiments relate to magnetic memory devices and methods for manufacturing the same. The magnetic memory device includes a magnetic tunnel junction layer including a first magnetic layer, a second magnetic layer, and a first tunnel barrier layer between the first and second magnetic layers. The second magnetic layer is disposed on the first tunnel barrier layer and is in direct contact with the first tunnel barrier layer. The second magnetic layer includes cobalt-iron-beryllium (CoFeBe). A beryllium content of CoFeBe in the second magnetic layer ranges from about 2 at % to about 15 at %.
Method for producing a piezoelectric multilayer component and a piezoelectric multilayer component
A piezoelectric multilayer component having a stack of sintered piezoelectric layers and inner electrodes arranged between the piezoelectric layers. A region which has poling cracks is present on the surface of at least one electrode, and the poling cracks are separated from a surface of at least one of the inner electrodes by the region having the poling cracks.
Electronic component package and method for manufacturing the same
A method for manufacturing an electronic component package. The method includes (i) providing a package precursor in which an electronic component is embedded such that an electrode of the electronic component is exposed at a surface of a sealing resin layer; (ii) forming a first metal plating layer such that the first metal plating layer is in contact with the exposed surface of the electrode of the electronic component; (iii) disposing a metal foil in face-to-face spaced relationship with respect to the first metal plating layer; and (iv) forming a second metal plating layer. In step (iv), the second metal plating layer is formed so as to fill a clearance between the first metal plating layer and the metal foil, thereby integrating the metal foil, the first metal plating layer and the second metal plating layer with each other.
