摘要： A GMR spin valve is provided for reading a magnetic signal from a magnetic recording medium. The spin valve includes a non-magnetic layer such as for example copper, separated by first and second magnetic layers. The spin valve includes a pinned magnetic layer and a free magnetic layer, the resistance of the spin valve changing with the relative angle between the direction of magnetization of free and pinned layers. Extremely smooth surfaces are provided at the interfaces between the non-magnetic layer and the adjacent magnetic layers. This smooth interface greatly enhances the performance and reliability of the spin valve by allowing extremely tight control of the thickness of the non-magnetic layer and by preventing atomic diffusion between the non-magnetic and magnetic layers. This smooth interface is achieved by including a surfactant in the deposition of the non-magnetic layer.

摘要： The method and system for providing a spin tunneling element are disclosed. The method and system include depositing a pinned layer, a barrier layer, and a free layer. The barrier layer has a first crystal structure and a texture. The free layer includes a first ferromagnetic layer and a second ferromagnetic layer. The first ferromagnetic is adjacent to the second ferromagnetic layer and between the second ferromagnetic layer and the barrier layer. The first ferromagnetic layer has the first crystal structure and the texture, while the second ferromagnetic layer has a second crystal structure different from the first crystal structure.

摘要： Optical multiplexers and demultiplexers are provided. In one implementation an apparatus is provided. The apparatus includes a first laser diode pair, a second laser diode pair, a polarization rotator coupled between the first and the second laser diode pairs, and an output port. The first and second laser diode pairs include a first laser diode, a polarization beam splitter, a first quarter waveplate, a filter; a second quarter waveplate, and a second laser diode. The first and second laser diode pairs are coupled to the polarization rotator at the polarization beam splitter of each laser diode pair. In one implementation the apparatus is operable to multiplex distinct light signals emitted from the first and second laser diodes. In another implementation, an apparatus is provided that is operable to demultiplex an input light beam having a plurality of distinct channels.
