|Issue Date:||Jul-2001||Citation:||Wang, J.P., Shan, Z.S., Piramanayagam, S.N., Chong, T.C. (2001-07). Anti-ferromagnetic coupling effects on energy barrier and reversal properties of recording media. IEEE Transactions on Magnetics 37 (4 I) : 1445-1448. ScholarBank@NUS Repository. https://doi.org/10.1109/20.950866||Abstract:||Analytical solutions for coercivity HCM1, HCM2, effective (Mrt)eff, energy-harrier and effective thermal stability factor as a function of coupling constant J and other film parameters have been derived for two coupled ferromagnetic layers (FM-FM layer) with different magnetic properties for the first time. The condition for reduced effective (Mrt)eff is analyzed. These results are valuable for laminated antiferromagnetically coupled media design. This may open up a channel to raise thermal stability significantly while maintaining lower noise for longitudinal recording media.||Source Title:||IEEE Transactions on Magnetics||URI:||http://scholarbank.nus.edu.sg/handle/10635/83495||ISSN:||00189464||DOI:||10.1109/20.950866|
