In order to improve the recording efficiency in current perpendicular recording media, it is important to reduce the distance from the head to soft underlayer. In this paper, a soft magnetic intermediate layer is proposed to partially replace the presently used Ru intermediate layer. The new soft magnetic intermediate layer serves two purposes, which are as follows: 1 to decrease the thickness ...

Core reuse is an emerging IC design style which enables rapid development of highly complex ICs. Reusable circuit cores come in two basic varieties, hard and soft. Hard cores are optimized for area and performance and are not modifiable by the user, whereas soft cores are user modifiable. If soft cores do not contain testability (i.e. scan/BIST), it can be inserted into the core by the user. Ha...

In this study, the comparative role of nano‐ and micro‐sized Cu powder in exploring the influence on the tribo‐performance of friction materials in the form of brake‐pads is discussed. Two friction composites were developed by keeping allthe ingredients constant and varying the size of the selected filler (copper powder). The developed micro‐composite contained 10 % ...

Compositionally graded cylinders comprising FeCo-2V, a soft magnetic alloy, and 316L stainless steel, were produced by directed energy deposition incorporating two different gradient lengths. Five distinct regions in the microstructure observed both as-printed annealed gradients. When normalized for length, gradients showed similar grain size microhardness profiles. In tensile tests, samples fa...

Here we report a magnetic composite nanocatalyst (MP@NiSiO/Pd) with a rattle type nanostructure. The nickel silicate shell encapsulated magnetic core (MP@NiSiO) rattle particles were synthesized by using a facile templating method and the Pd nanocrystals with different sizes can be directly immobilized onto the MP@NiSiO rattles without using any surfactant or capping reagents. X-Ray powder Diff...

In modern AC technologies, improving the power efficiency of soft magnetic core materials is a key factor. Powder metallurgy offers promising alternative for these applications: Soft Magnetic Composites are compacted iron-based powders, each iron particle being electrically insulated from its neighbours by superficial layer. Accordingly, thermal stability insulating layers used plays an essenti...

objective: the aim of this in vitrostudy was to evaluate the effect of the type of solvent in silane solution on microtensile bond strength of fiber posts to composite resin cores af-ter application of 24% hydrogen peroxide. materials and methods: eighteen white fiber posts, immersed in 24% hydrogen peroxide were divided into three groups (n=6). in the group a post surfaces were silanized with ...
