Abstract

Buluş konusu, manyeto-optik Kerr etkisi ölçümleri için çok fonksiyonlu örnek tutucusu (6) ve yüksek çözünürlüklü deteksiyon sistemi örnek düzleminde ve örnek düzlemine dik yönde mıknatıslanmaya sahip ölçülecek numunelerin (18) mıknatıslanma eğrilerini belirlemek amacı ile geliştirilmiştir. Çok fonksiyonlu örnek tutucusu (6) sayesinde, sistem Boyuna-MOKE geometrisinden Kutupsal-MOKE geometrisine kolaylıkla dönüştürülebilmektedir. Yine çok fonksiyonlu örnek tutucuda (6) yer alan 360 derece örnek döndürücü adım motor (7) yardımıyla örnek düzleminde açıya bağlı mıknatıslanma ölçümleri yapılabilmektedir. Bununla birlikte, sinyal ayırıcı yükselteç (Lock-in amplifier) (15) de kullanıldığı bir filtreleme sistemi yardımıyla mıknatıslanması çok zayıf örneklerde bile yüksek hassasiyetli ölçüm sonuçları elde edilebilmektedir.The subject of the invention, the multifunctional sample holder (6) and high-resolution detection system for magneto-optic Kerr effect measurements have been developed to determine the magnetization curves of the samples to be measured (18) in the sample plane and in the direction perpendicular to the sample plane. Thanks to the multi-functional sample holder (6), the system can be easily converted from Longitudinal-MOKE geometry to Polar-MOKE geometry. Again, with the help of the 360 degree sample rotating step motor (7) located in the multi-functional sample holder (6), angle-dependent magnetization measurements can be made in the sample plane. However, with the help of a filtering system in which a signal separator amplifier (15) is also used, high-precision measurement results can be obtained even with samples whose magnetization is very weak.
