摘　　要：This study explores the presence of diverse phase diagrams and hysteresis characteristics,as well as their dependencies on segment dilution,in an Ising-type core/shell segmented nanostructure.The magnetic and hysteretic behavior of the nanostructure was carefully investigated by employing the effective-field theory and its respective diluted parameters.The phase diagrams reveal characteristic phenomena that are influenced by the dilution parameters.Specifically,this study examined the variations in phase transitions and tricritical points by altering the dilution and physical parameters of the segments.The investigation also encompasses an examination of the hysteresis characteristics,including the hysteresis loop,coercivity,and remanence,in relation to the segment dilution dependence of the segmented nanowire.It was discovered that as the temperature rises,the hysteresis loop areas diminish.However,intriguingly,at specific dilution and crystal area values,the hysteresis loop areas exhibit an augmentation.
