In this paper, we study the influence of the physical parameters on the thermal and magnetic properties of a nano-particle of bi-fullerene-like structure X[Formula: see text]-Y[Formula: see text] separated by nonmagnetic spherical surfaces, using the Metropolis Monte Carlo (MC) simulations. The coupling between the two spheres containing the spins [Formula: see text] = 3/2 and the spins S = 7/2 belongs to the core and shell, respectively. This study is based on the RKKY (Ruderman–Kittel–Kasuya–Yoshida) interaction type. To complete this work, we carry out the hysteresis cycles of the studied system for different nonmagnetic surface (NMS) numbers.

5-ethoxymethyl-8-hydroxyquinoline was synthesized and characterized using spectroscopic methods ( 1 H, 13C NMR, IR). The crystal structure determined at room temperature (295 K) by means of X-ray powder diffraction is orthorhombic, with space group Pbca and eight molecules per unit cell (Z = 8, Z 0 = 1). The lattice parameters are: a = 7.9551(12) Å , b = 17.981(3) Å , c = 15.125(2) Å and V = 2163.5(6) Å 3 . Geometric parameters and properties depending on the charge distribution around the different types of donors and acceptors bonds within the molecule are calculated by density functional theory (DFT/B3LYP) and Hartree-Fock methods. Atomic charges and dipole moment value permit qualitative predictions about high reactivity of this molecule. The 5-ethoxymethyl-8-hydroxyquinoline adopts a non-planar structure in the solid state and the molecule is stabilized by contact system as p-p stacking interactions, weak intra and intermolecular H-Bonding O-HÁÁÁN and C-HÁÁÁO types, this latter involving the rings of both adjacent molecules in plans with a gap from 0.638 Å .
