Micromagnetic Modeling

Using the methods of micromagnetic modeling, the dependence of the structure and energy of a domain wall localized in the magnetic bridge between ferromagnetic films on the geometric parameters of the system has been investigated. The effect of displacement and change in the shape of the magnetization curve of the soft magnetic layer caused by the exchange interaction with the magnetic hard layer through a magnetic filament has been demonstrated.

The Monte Carlo Method

Investigation of the magnetization reversal of a hard/soft magnetic bilayer in an external magnetic field was performed by the Monte Carlo method. The magnetization reversal curves of the magnetic bilayer are plotted for various values of the thickness of the soft magnetic layer. Also the effect of the intralayer exchange interaction and the anisotropy constant on the magnetization reversal processes was studied. The phase diagrams of the magnetic bilayer are plotted.

Compelling Experimental Evidence

Local polarization of magnetic materials has become a well-known and widely used method for storing binary information. Numerous applications in our daily life such as credit cards, computer hard drives, and the popular magnetic drawing board toy, rely on this principle. In this work, we review the recent advances on the magnetic recording of inhomogeneous magnetic landscapes produced by superconducting films. We summarize the current compelling experimental evidence showing that magnetic recording can be applied for imprinting in a soft magnetic layer the flux trajectory taking place in a superconducting layer at cryogenic temperatures. This approach enables the ex situ observation at room temperature of the imprinted magnetic flux landscape obtained below the critical temperature of the superconducting state. The undeniable appeal of the proposed technique lies in its simplicity and the potential to improve the spatial resolution, possibly down to the scale of a few vortices.

Saturation Induction

The dynamic properties of the soft magnetic composite material in the frequency range up to 100 kHz with a change in the thickness of the insulating layer and the size of iron particles were investigated. It is shown that with an increase in the thickness of the insulating layer, the loss for remagnetization decreases, but at the same time there is a decrease in the magnetic value of the saturation induction and magnetic permeability. Therefore, that the decision to reduce losses by increasing the thickness of the insulating coating is not always the best solution. It is preferable to achieve a reduction losses for remagnetization due to an increase in the specific resistance of the insulating layer with its minimum thickness.

New Applications

This paper is devoted to the investigation of crystalline structure, surface morphology, magnetic anisotropy, coercive force and domain structure of spin-valves with a single and double MgO barrier layers. It is shown that domain structure and magnetization reversal are the same for both systems, but otherwise the behavior of tunnel magnetoresistance is different. The approach to control magnetic anisotropy in soft magnetic layer using temperature annealing is demonstrated. It makes these structures possible for new applications in nanoelectronics.
