【摘要】We further calculate the dependence of xT on T in high magnetic

fields,where

X

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 xT maximum and the magnetic field.Moreover,we simply analyze its physical meaning by our approach.`` 【总页数】3页(620-622)
