Abstract: Methods of forming near field transducers (NFTs) including electrodepositing a plasmonic material.

Abstract: Cryoprotective compositions with magnetic nanowires and cryoprotective agents are used to cryopreserve biomaterials. The biomaterials in the cryoprotective composition are rapidly and uniformly heated during warming to minimize damage due to cracking and/or devitrification. The nanowires are CoFe nanowires. The nanowires may be aligned parallel to the alternating magnetic field to increase the specific absorption rate of the nanowires. The methods include warming the cryopreserved biomaterial in the cryopreserved composition at a rate higher than the critical warming rate using an alternating magnetic field.

Abstract: A method is disclosed for defining discrete magnetic and non-magnetic regions on the magnetic film layer of a storage media substrate. The method applies anodic oxidation of a cobalt-containing magnetic film layer to remove cobalt, followed by controlled deposition of a non-magnetic matrix into the regions where the cobalt has been removed. Deposition may either be electrodeposition, collimated vacuum deposition, or other methods depending upon the composition of the non-magnetic matrix being deposited. The method may be performed in a single electrochemical cell.

Abstract: A contact pad includes a first layer of material with a first yield strength and a second layer of material with a second yield strength is laminated to the first layer. A third yield strength of the laminated composite of the first layer and the second layer exceeds the first yield strength and the second yield strength due to the Hall-Petch phenomenon. An overcoat covers an edge of the first layer and the second layer of the contact pad to prevent wear. A method of creating the contact pad or other microelectronic structure includes depositing a first layer of material with a first yield strength on a substrate. A second layer of material with a second yield strength is deposited on the first layer. An edge of the first layer and the second layer is coated with an overcoat material to prevent wear of the first and second layers.
