Magnetic Properties of Fe49Co33Ni18Nanowire ArraysStudied by First-Order Reversal Curve Diagrams
Fe49Co33Ni18 nanowire arrays (175 nm in diameter and lengths ranging from 5 to 32μm) were fabricated into nanopores of hard-anodized aluminum oxide templates using pulsed ac electrodeposition technique. Hysteresis loop measurements indicated that increasing the length decreases coercivity and squareness values (from 274 Oe and 0.58 to200 Oe and 0.105, respective...
متن کاملFirst-order reversal-curve diagrams and reversible magnetization
First-order reversal curve ~FORC! diagrams have recently been used for the characterization of magnetic systems in both geology and physics. However, the FORC distribution involves a mixed second derivative which reduces the reversible component of the magnetization to zero. As a result, the FORC distribution is not properly normalized. Furthermore, the calculation of the FORC distribution beco...

در این تحقیق برای اولین بار از قالب آلومینای آندی که به روش آندایز سخت با الکترولیت اسید اگزالیک در ولتاژ130 ولت تولید شده بود به عنوان قالب برای ساخت نانو سیمهای آلیاژی fe0.5co0.5استفاده شد. برای مطالعه ی میزان و شدت برهمکنش های مغناطواستاتیک بین آرایه ی نانوسیمها از سیستم آنالیز forc که با مشارکت و پشتیبانی شرکت مغناطیس دقیق کویر برای اولین بار در غرب آسیا طراحی و ساخته شده است، استفاده گردید...
15 صفحه اولUnderstandingfinemagnetic particle systems through use of first-order reversal curve diagrams
First-order reversal curve (FORC) diagrams are constructed from a class of partial magnetic hysteresis loops known as first-order reversal curves and are used to understand magnetization processes in fine magnetic particle systems. A wide-ranging literature that is pertinent to interpretation of FORC diagrams has been published in the geophysical and solid-state physics literature over the past...
