Microwave assisted magnetic recording has been proposed as a next generation recording technology, which utilizes a spin torque oscillator (STO) imbedded between write pole and trailing shield for generating high frequency ac field [1] [2].
One of the fundamental questions is how we can enhance our relationships with the people in our social networks. The combination of frequent engagement, deep interaction, and time spent together are what constitute to build a stronger relationship. With this knowledge in mind, it is not surprising to see many scholars claim that social networking sites may help us to re-connect some lost relationships,...
Embedded Mask Patterning (EMP) method uses a plasma etching process to form ultra-small but thermally stable isolated L10-FePt magnetic grains with embedded Ru hardmask1,2. It has been demonstrated as a promising and highly cost effective solution to fabricate the ultra-high density magnetic media for the next generation hard-disk drive technology, such as heat-assisted magnetic recording (HAMR)....
In previous work, we reported on the fabrication of a regular template for the controlled two-phase growth of conventional CoPt-SiO2 PMR media. The template consisted of dome-morphology patterned into a Platinum FCC (111) textured thin film. When CoPt-SiO2 was sputtered, the artificially patterned domes acted as sites on which the CoPt grains grew, with the segregant growing within the trenches between...
Heat-assisted magnetic recording (HAMR) has been widely touted as a leading candidate for enabling the next generation of ultra-high density data storage [1]. To fully assess the advantage and potential of HAMR technology and to understand the physics of the HAMR recording process, extensive Landau-Lifshitz-Bloch (LLB) equation-based micromagnetic modeling has been conducted [2]. Fundamental recording...
