Insight into the magnetic behavior and magnetocaloric effect of a borophene monolayer

Abstract

The successful discovery of borophene has opened a new door for the development of two-dimensional materials. Owing to its excellent chemical, electronic and thermal properties, borophene has shown considerable potential in supercapacitor, hydrogen-storage and battery. In this paper, the thermodynamic characteristics and magnetocaloric effect of a borophene are studied specifically by using Monte Carlo method. We find that there is an opposite impact between the spin quantum number and crystal field on the magnetization, magnetic susceptibility, specific heat and magnetic entropy of the system. Moreover, increasing the spin quantum number or decreasing the absolute value of the crystal field can improve the relative cooling power (RCP), the coercivity (hc) and the remanence (MR) and the area of the loop.

The impact of segment dilution on the magnetic and hysteretic properties of ferrimagnetic (1/2-1) segmented Ising nanowire

“…In this subsection, the hysteresis characteristics of the system are examined with regard to their dependence on temperature, segment dilutions, and crystal field and are presented in figures 6-8. The investigation of hysteresis loops in lowdimensional nanostructures has been conducted through the utilization of MCS [43,[65][66][67][68][69]. Kantar [70] examined the thermal and magnetic properties of a hexagonal Ising nanowire and various other systems [25,71] using EFT.…”
