Abstract: 本論文主要研究鈷-鈀合金薄膜之極向柯爾效應、矯頑磁力,以及反射率等磁光特性。基板為0211玻璃基板加熱溫度為250oC。薄膜厚度從5nm到100nm。藉由改變鈷比例,薄膜厚度,以及入射光子能量會影響樣品的磁性。根據磁光柯爾效應理論,柯爾轉角θK會正比於磁性物質受磁化的大小。因此藉由量測θK對磁場關係,便可以得到磁性物質的磁化曲線。 由本實驗結果得知Co15Pd85 膜厚300Å為較適合的磁記錄材料。
The purpose of this thesis is to study the magnetic optical properties of the polar kerr effect, coercive force and reflectance of the Co-Pd alloy films onto a 0211 Corning glass substrates, held at a temperature of Ts=250oC. The range of the film thickness is from 5 to 100nm. Discuss the effects with respect to the magnetic properties of Co-Pd alloy films when the value of Co contents, film thickness and incident photon energy is changed. Based on the theory of magneto-optical Kerr effect, Kerr rotation θK is proportional to the magnetization of a magnetic material. Therefore, by measuring θK versus the applied magnetic field H, the magnetization curve of a magnetic material will be presented. Our experimental results, the Co-15 at.% Pd alloy with film thickness of 300Å is a better magnetic recording material.
