| Abstract |
| | The present study is devoted to modeling the magnetization vector dynamics in the free layer of magnetic elements included in the architecture of the MRAM and HMDD read heads. The qualitative analysis of the system of equations describing the magnetization vector dynamics is carried out. As base materials, six soft and four hard ferromagnetics with longitudinal and perpendicular anisotropy are considered. Calculation of critical currents and fields showed that the most energy-efficient configuration of the anisotropy axis for the MRAM and HMDD is parallel to the plane of the layers. As a result of numerical calculations of the switching time, it was found that among the materials considered, the most suitable for the MRAM cell is Co80Gd20 alloy, and for the HMDD read head is Fe60Co20B20. |
