| Abstract: | In this paper, we investigate the spin orientation effects on the magnetic properties of the Carbon diamond nanolattice (CDNL) by using Kaneyoshi approach (KA) within the effective field theory. In our calculations, we use the normalized lattice constant (na = 3.566 = a/1 A0) which is obtained from the real lattice constant (a = 3.566 A0) of the CDNL. The CDNL has three different magnetic atoms according to nearest-neighbor, and they are defined as corner atoms (mc), face atoms (mf) and inner atoms (mi). For mc, mf and mi, the CDNL has eight spin orientations as +++ (↑↑↑), −++ (↓↑↑), ++− (↑↑↓), −+− (↓↑↓), −−+ (↓↓↑), −−− (↓↓↓), +−− (↑↓↓) and +−+ (↑↓↑), respectively. We find that the CDNL has two kinds of critical temperature behaviors, we call them as high critical temperature behavior (HCTB) for the first four spin orientations and low critical temperature behavior (LCTB) for the second four spin orientations. However, the CDNL exhibits ferromagnetic (FM), antiferromagnetic (AFM), superconductivity (SC), discontinuous diamagnetic (DM) and discontinuous paramagnetic (PM) hysteresis behaviors according to the spin orientation of its atoms. Therefore, we suggest that it is possible to obtain different magnetic behaviors and artificial magnetism from the Carbon and Carbon-based materials with the spin orientations of their atoms. |
