Özet:

 


 
                         We implement Monte Carlo simulations to determine dynamic 
phase transition features of both cubical and spherical nanoparticles 
composed of spin-1/2 cores surrounded by a spin-1 shell layer. The particles 
are subjected to an oscillating magnetic field. We plan these particles such 
that they have similar volumes. It is observed that the nonequilibrium 
magnetic phase transition temperatures of the particles with similar volumes 
explicitly depend on their geometrical shapes as well as the system 
parameters. The cubic one has a higher transition temperature than the 
spherical one for the small interface coupling, whereas the transition 
temperature of the spherical particle becomes higher than that of the cubic 
one with further increment in antiferromagnetic coupling. We also analyze 
the magnetic features of the particles, such as dynamic remanence and 
coercivity treatments. Our simulation results suggest that the spherical 
particle has almost the same coercivity behavior as the cubic one for some 
considered system parameters. However, there are some differences in the 
context of remanence behaviors between spherical and cubic core-shell 
nanoparticles.
