摘要:
A magnetoresistive device having a high giant magnetoresistance (GMR) value and a moderate low resistance area product (RA) includes a first magnetic layer, a second magnetic layer, and a current confined path (CCP) spacer layer positioned between the first magnetic layer and the second magnetic layer. The spacer layer includes copper current confined paths extending between the first magnetic layer and the second magnetic layer in a matrix of magnesium oxide. The spacer layer is formed by a mixture copper and magnesium oxide, which is heattreated to form the copper current confined paths within the magnesium oxide matrix.
摘要:
In some embodiments, a current perpendicular to the plane giant magneto-resistance (CPP GMR) read sensor may include a reference layer and/or a free layer that includes a plurality of sub-layers. For example, at least one of the reference layer or free layer may include a first ferromagnetic sub-layer, a second ferromagnetic sub-layer, and a Heusler alloy layer located between the first ferromagnetic sub-layer and the second ferromagnetic sub-layer. In some embodiments, a CPP GMR read sensor may include a current closed path (CCP) spacer layer between the reference layer and the free layer. The CCP spacer layer may include Ag and Al2O3. In further embodiments, a CPP GMR read sensor may include a Heusler alloy free layer, a Heusler alloy reference layer, and a CCP spacer layer.

摘要:
A magnetic sensor comprising a first shield and a second shield and a sensor stack between the first and the second shield, the sensor stack having a plurality of layers wherein at least one layer is annealed using in-situ rapid thermal annealing. In one implementation of the magnetic sensor a seed layer is annealed using in-situ rapid thermal annealing. Alternatively, one of a barrier layer, an antiferromagnetic (AFM) layer, and a cap layer is annealed using in-situ rapid thermal annealing.

摘要:
A magnetic sensor assembly includes first and second shields each comprised of a magnetic material. The first and second shields define a physical shield-to-shield spacing. A sensor stack is disposed between the first and second shields and includes a seed layer adjacent the first shield, a cap layer adjacent the second shield, and a magnetic sensor between the seed layer and the cap layer. At least a portion of the seed layer and/or the cap layer comprises a magnetic material to provide an effective shield-to-shield spacing of the magnetic sensor assembly that is less than the physical shield-to-shield spacing.
摘要:
An aerator assembly for an animal watering device having a rotor mount removably inserted in a discharge opening of a cover of the device and a rotor carried by the mount that is rotated by discharged water. The mount includes a conduit having one end inserted in the cover and an outlet at its opposite end conveying a discharged stream of water against rotor baffles causing rotation. The mount includes an arm that offsets an axis of rotation of the rotor relative to the stream so water impinges against a baffle. A pin can be included that engages the arm that is received through a rotor hub rotatively attaching the rotor to the arm. Such an aerator not only aerates water discharged during fountain operation, it also reduces noise by reducing splashing. The present invention is also directed to a pet fountain equipped with such an aerator assembly.

A pet fountain assembly that includes a cover with a drinking bowl formed therein that straddles a sidewall of a basin that can be user-provided enclosing a pump within a pumping chamber defined therebetween. The cover has a downwardly extending sidewall divided by openings that can be generally U-shaped or V-shaped into a plurality of supports on which the cover. In a preferred embodiment, one of the supports is disposed outboard the basin sidewall resting on the ground and another one of the supports is disposed inboard the basin sidewall resting on a bottom of the basin providing a water passage enabling water from the basin to reach the pump. The inboard support can provide an overflow spillway as well as define a shroud disposed between the pump and water in a lower drinking bowl of the basin. The basin can include an outwardly offset seat that locates the pump.
