Understanding on coercivity behavior of M-type strontium hexaferrite through thin-film experiment and micromagnetic modeling

We report on the magnetization reversal and coercivity behavior of M-type strontium hexaferrite (SrM) granular structure through thin-film experiment and micromagnetic simulation. We found that with decreasing film thickness (t), the coercivity increases gradually to its maximum of 5.2 kOe at t = 20...

description We report on the magnetization reversal and coercivity behavior of M-type strontium hexaferrite (SrM) granular structure through thin-film experiment and micromagnetic simulation. We found that with decreasing film thickness (t), the coercivity increases gradually to its maximum of 5.2 kOe at t = 200 nm, turns to decrease at t > 100 nm, and then it decreases rather rapidly at t
