Local magnetic structures induced by inhomogeneities of the lattice in S = 1/2 bond-alternating chains and response to time-dependent magnetic field with a random noise

چکیده
We study effect of inhomogeneities of the lattice in the S = 1/2 bondalternating chain by using a quantum Monte Carlo method and an exact diagonalization method. We adopt a defect in the alternating order as the inhomogeneity and we call it ‘‘bond impurity’’. Local magnetic structures induced by the bond impurities are investigated both in the ground state and

Micromachining the Aluminium Tubes Using Abrasive Finishing in Alternating Magnetic Field
This study introduced a method based on magnetic field assisted finishing mechanism for micromachining the inner surfaces of Aluminum tubes. In this approach, using the alternating magnetic field of an AC electromotor, abrasive particles were formed as Magnetic Rods (Magnetic Clusters) and surface micromachining was carried out by the dynamic particular pattern made by an alternating magnetic f...
متن کاملInduced tissue cell death by magnetic nanoparticle hyperthermia for cancer treatment: an in silico study
In this paper, we simulate magnetic hyperthermia process on a mathematical phantom model representing cancer tumor and its surrounding healthy tissues. The temperature distribution throughout the phantom model is obtained by solving the bio-heat equations and the consequent cell death amount is calculated using correlations between the tissue local temperature and the cell death rate. To have a...
متن کاملLocal magnetic structure due to inhomogeneity of interaction in S = 1 / 2 antiferromagnetic chain
We study the magnetic properties of S = 1/2 antiferromagnetic Heisenberg chains with inhomogeneity of interaction. Using a quantum Monte Carlo method and an exact diagonalization method, we study bond-impurity effect in the uniform S = 1/2 chain and also in the bond-alternating chain. Here ‘bond impurity’ means a bond with strength different from those in the bulk or a defect in the alternating...
متن کاملMagnetic Properties in a Spin-1 Random Transverse Ising Model on Square Lattice
In this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4), ferromagnetic Ising system consisting of magnetic atoms with spin-1. This study is done using the effectivefield theory (EFT) with correlations method. The equations are derived using...
متن کاملNew Achievements in Fe3O4 Nanofluid Fully Developed Forced Convection Heat Transfer under the Effect of a Magnetic Field: An Experimental Study
Fe3O4 nanofluid fully developed forced convection inside a copper tube is empirically investigated under the effect of a magnetic field. All of the investigations are performed under laminar flow regime (670≤Re≤1700) and thermal boundary conditions of the tube with uniform thermal flux. The tube is under the effect of a magnetic field in certain points. This research aims to study the effect of...
