Special Issue Information

Dear Colleagues,

Conventional electronic devices process information by manipulating the degrees of freedom of electronic charge. However, the presence of quantum effects has led to the failure of Moore's Law, which has led to a bottleneck in the miniaturization and integration of electronic devices based on the degrees of freedom of charge. Since electrons have two endowed properties, namely, charge freedom and spin freedom, new electronic devices based on the degrees of freedom of electron spin have the advantages of strong non-volatility, fast information processing speed, low power consumption, good stability, and high degree of integration compared with traditional electronic devices. The carriers in magnetic materials have spin-polarization characteristics, so the two degrees of freedom of electrons can be used simultaneously to develop a new information processing technology model that integrates information transmission, processing, and storage and then develops new microelectronic devices. Therefore, these magnetic materials have broad application prospects as a new generation of electronic materials.

In this Special Issue, we welcome articles that focus on the calculations of magnetic materials by first-principles and Monte Carlo methods. Through theoretical simulations, the intrinsic relationship between the microstructure, components, and macroscopic mechanical, thermodynamic, and thermoelectric properties of magnetic materials can be revealed. At the same time, the influence of surface and interface effects on the above properties is revealed, which in turn provides a scientific basis for the application of magnetic materials in spintronic devices.

The formation and evolution of SmCo5/Sm2Co17 (1:5H/2:17R/H) cellular structures play an essential role in understanding the coercivity of Sm-Co magnets. Herein, the pristine and different elemental-doped 1:5/2:17R and 1:5/2:17H interfaces are investigated to evaluate the elemental site preferences, interface configurations, and magnetic properties in Sm2Co17-type magnets with general alloy elements M (M = Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Al, Si, and Ga). Comparing the calculated results of 1:5/2:17H with those of the 1:5/2:17R interface, we found that Cu and Mn always segregate at the 1:5 phase, and Ga elements first appear at the 1:5 phase in 1:5/2:17H and then change to the 2:17 phase in 1:5/2:17R. While Ti, V, Fe, Zn, Al, and Si elements always tend to segregate at the 2:17 phase, Ni first segregates at the 2:17 phase in 1:5/2:17H and then occupies the 1:5 phase of 1:5/2:17R. The 1:5/2:17H interface along the c-axis expands about 1.98~3.28%, while the 1:5/2:17R interface slightly shrinks about 0.04~0.87% after element doping. This suggests that different interface stress behaviors exist for high-temperature and room-temperature phase Sm2Co17-type magnets. Furthermore, Mn, Fe, and Ga doping improved the saturation magnetization strength. Our results provide new insights into understanding the effect of elemental doping at the interfaces of 1:5H/2:17R cellular structures. Full article
