The main goal of the present study is to identify characteristics of the inter-station horizontal magnetic responses and the vertical magnetic data, as two types of magnetotelluric transfer functions, in the modeling procedure. Through consideration of model responses and two-dimensional inversion of synthetic data, sensitivity of the data components in detecting different geophysical structure...

Structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu)  were studied  for each of three magnetic configurations nonmagnetic, ferromagnetic, and antiferromagnetic by using density functional theory in generalized gradient approximations (GGA) and strong correlation correction (GGA + U). Due to magnetic transition from antiferromagnetic to nonmagnetic phase, an electr...

In this work, La0.6Sr0.4MnO3 manganite particles with nano and micro scales were prepared by Sol-gel and solid state reaction methods. The results from X-ray diffraction analysis by Fullprof software showed that the samples have been crystallized in the rhombohedral structure with (R-3C) space group. Investigation of magnetic properties showed that this compound belong to soft ferromagnetic mat...

Nanomagnetism is a branch of nanotechnology, which studies the magnetic properties of nanoparticles. Single-domain superparamagnetim, superferromagnetism and superspin glasses are different magnetic states which have been observed in a system of nanoparticles. Each of these magnetic states has unique features which determines the application range of magnetic nanoparticles assembly. Shell of na...

 We present and compare the magnetic structures of limit compounds, between the ferromagnetism and antiferromagnetism in the pseudobinary compounds of type RNi/Pt/Cu, where R = Tb, Gd, Nd or Ce, appearing when we substitute the transition metal. All of them are examples of complex magnetic structures as the result of different magnetic interactions, inhomogeneities and disorder. This overview p...

This research study presents a numerical study on forced convection heat transfer of an aqueous ferrofluid passing through a circular copper tube in the presence of an alternating magnetic field. The flow passes through the tube under a uniform heat flux and laminar flow conditions. The primary objective was to intensify the particle migration and disturbance of the boundary layer by utilizing ...
