The influence on the magnetism and the electron spin resonance ( esr ) over a wide range of composition and temperature have been studied systematically . an obvious symmetric esr signal with a lorentzian lineshape in the paramagnetic regime is observed 本论文边过选择磁性离子替代，着眼点在于讨论衫杂离子的磁性效应，实验发现掺杂使样品的磁结构发生变化，且在低温时出现磁化强度峰，用掺杂离子自旋旋转对此进行了解释。
