An exchange coupled composite media structure proposed previously seems to address both the issue of Tc variation in FePt as well as poor SNR/User Density during the HAMR process. Here we examine a thinner 3-6 nm structure that is likely easier to fabricate than the previous 13. 5 nm thick structure. https://www.spidertattooz.com/Superdry-Organic-Cotton-Essential-Baseball-L-S-T-shirt/
