Abstract: | Heat assisted magnetization reversal on perpendicular magnitized nano-dots has been studied by solved Landau Lifshift-Gilbert equation for magnetic recording application. The heat assisted magnetization reversal scheme has been proven to be effectively reduces threshold field down to 90%. Otherwise, this field doesn't depend on heating time. To understand a read-write information process, cooling time dependence of threshold field has been evaluated. As a result, the threshold field depend on the cooling time and become constant after 300 ps. This result corresponds to data transfer of Hard Disc Drive about 30 Gb/s. Telah dilakukan evaluasi mode magnetisasi reversal berbantukan panas pada nanodot magnetik beranisotopi tegak lurus dengan menyelesaikan persamaan Landau Lifshift-Gilbert untuk aplikasi perekaman magnetik. Skema magnetisasi reversal berbantukan panas terbukti efektif menurunkan medan threshold hingga 90%. Namun demikian, medan threshold tidak bergantung pada lamanya pemanasan. Untuk lebih memahami proses baca-tulis informasi, telah dilakukan evaluasi pola hubungan medan threshold terhadap lamanya pendinginan. Dan didapatkan bahwa medan ini bergantung pada lamanya pendinginan dan menjadi konstan setelah 300 ps. Hasil ini terkait dengan kecepatan transfer data pada Hard Disc Drive dalam orde Gb/s. |
