Abstract

•Dynamic behaviors of mixed spin HIN system are obtained within the EFT.•The system exhibits i, p and nm fundamental phases.•The dynamic phase diagrams are presented in (h, T), (D, T), (ΔS, T) and (r, T) planes.•The dynamic phase diagrams exhibit the dynamic tricritical point (TCP).•Different dynamic compensation types are obtained.

The dynamic behaviors of a mixed spin (1/2–1) hexagonal Ising nanowire (HIN) with core–shell structure in the presence of a time dependent magnetic field are investigated by using the effective-field theory with correlations based on the Glauber-type stochastic dynamics (DEFT). According to the values of interaction parameters, temperature dependence of the dynamic magnetizations, the hysteresis loop areas and the dynamic correlations are investigated to characterize the nature (first- or second-order) of the dynamic phase transitions (DPTs). Dynamic phase diagrams, including compensation points, are also obtained. Moreover, from the thermal variations of the dynamic total magnetization, the five compensation types can be found under certain conditions, namely the Q-, R-, S-, P-, and N-types.
