文摘
- •
We study a spin-2 spin-5/2 Ising ferrimagnet with nearest, next-nearest interactions, and a crystal field.
- •
We calculate the phase diagram, indicating critical and compensation temperatures.
- •
We found that the compensation temperatures strongly depend on the interactions between the spins 2.
- •
Once the compensation temperature appears, it depends strongly on the crystal field.
