Abstract: Using the dynamic mean-field theory based on the Glauber-type stochastic dynamics, we investigate the dynamic critical magnetic properties of a core–shell hexagonal Ising nanotube system with spin-3/2 particles in the core and the mixed-shell (1, 1/2) under the constraint of an oscillating magnetic field. The time-dependent behaviors, thermal variations of magnetizations, dynamic phase diagrams, and hysteresis loops are studied in detail according to the system’s parameter values. Throughout the dynamical relaxations, critical properties such as dynamic first- and second-order phase transitions, magnetic compensation, tricritical point, critical end point, double critical end point, isolated critical point, triple point, and quadruple point are obtained. The hysteresis loops exhibit different topologies within the space parameters of the model considered. On the other hand, frequency analysis of the system response is studied in order to reveal its nonequilibrium properties. It is worth mentioning that our findings are in perfect agreement with those existing in the literature. This study shows the impressive character of composite materials in predicting the fascinating properties to be sought in the world of nanotechnology.
