Abstract
High field (>20kOe) multi-frequency, 75-95GHz, ferromagrictic resonance was used to determine the magnetocrystalline anisotropy and Gilbert damping parameter of two types of CoCrPtTa longitudinal recording media. The magnetocrystalline anisotropy as measured by FMR of both samples was 10.8 kOc which is larger than that measured from torque magnetometry which was 9.6kOe. We suggest that this difference is due to the presence of exchange coupling between the grains. (C) 2002 Elsevier Science B.V. All rights reserved.
