First order reversal curve studies of permanent magnets

First order reversal curve (FORC) diagrams are a useful tool to analyze the magnetization processes in magnetic materials. FORC diagrams are computed from measured first order reversal curves on sintered Nd 2 Fe 14 B magnets. It is shown that the FORC diagram simplifies if the first order reversal curves a desheared using the macroscopic demagnetizing field given by the geometry of the sample. ...

مطالعه برهمکنش مغناطواستاتیک نانووایرهای کبالت-آهن با استفاده از دیاگرامهای first order reversal curves (forc)

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...

Case studies for a first-order robust nonlinear programming formulation

In this paper, we conduct three case studies to assess the effectiveness of a recently proposed first-order method for robust nonlinear programming (Ref. 1). Three robust nonlinear programming problems were chosen from the literature using the criteria that results calculated using other methods must be available and the problems should be realistic, but fairly simple. Our studies show that the...

Bernoulli matrix approach for matrix differential models of first-order

The current paper contributes a novel framework for solving a class of linear matrix differential equations. To do so, the operational matrix of the derivative based on the shifted Bernoulli polynomials together with the collocation method are exploited to reduce the main problem to system of linear matrix equations. An error estimation of presented method is provided. Numerical experiments are...
