| Abstract: | We further calculate the dependence of χT on T in high magnetic fields,where χ denotes susceptibility and T is temperature,using our previous research work - Green function's decoupling approximate approach,for the one-dimensional ferrimagnetic chain with alternating spins 1 and 1/2.We find a linear correlation in certain range of magnetic field between the temperature of χT maximum and the magnetic field.Moreover,we simply analyze its physical meaning by our approach. |
