Magnetic properties and thermodynamics in a metallic nanotube

•A hexagonal metallic nanotube is composed of spin-3/2 inner layer and spin-1 outer layer.•Various types of magnetization curves depend on physical parameters and temperature.•We study the effects of physical parameters on the magnetic properties and thermodynamics.

A metallic nanotube composed of the ferromagnetic spin-3/2 inner shell and spin-1 outer shell with a ferrimagnetic interlayer coupling has been studied by using the effective-field theory with correlations (EFT). With both existence of the magnetic anisotropy and transverse field, we have studied effects of them on the magnetic properties and the thermodynamics. Some interesting phenomena have been found in the phase diagrams. At low temperature, the magnetization curves present different behaviors. Two compensation points have been found for the certain values of the system parameters in the system. The research results of metallic nanotubes may have potential applications in the fields of biomedicine and molecular devices.
