The magnetic nanotubes, which is one of the most important research topics in both statistical mechanics and material science, is widely used in the crucial areas due to the potential technological applications. Although there have been many studies on the equilibrium magnetic properties of various types of the magnetic nanotubes, the studies on the out-of-equilibrium magnetic properties are limited. Hence, the mean-field theory based on Glauber-type stochastic dynamics is applied to investigate the out-of-equilibrium magnetic properties of the mixed-spin (1, 3/2) hexagonal Ising nanotube with core–shell structure (HINT) in the presence of an oscillating magnetic field. We study numerically the non-equilibrium magnetic properties (the dynamic phase transitions, hysteresis loop areas, correlations, phase diagrams) of the HINT. The dynamic mean-field equations are derived from the Glauber dynamics intertwined with the mean-field theory. The time-varying average core and shell magnetizations are investigated to find the phases of the system. The temperature dependence of the dynamic order parameters is figured out for the purpose of qualifying the nature of the dynamic phase transitions and getting the dynamic phase transition points. Finally, the dynamic phase diagrams (DPDs) of the HINT are depicted in the plane of the oscillating magnetic field versus temperature, which contain four fundamental and six mixed phases. The DPDs also display some dynamic special points such as the dynamic tricritical, triple, quadruple points and some sort of reentrant phenomena, which strongly depend on interaction parameters.
