采用标准固相反应法合成了不同Al掺杂浓度的YMn 1-xAlxO 3多晶样品。研究了Al掺杂对磁性能的影响。磁化强度测试结果表明，随着Al 3+离子掺杂量的增加，样品的磁化强度增加，而计算的阻挫因子减小。随着Al掺杂量的增加，自旋玻璃行为变得越来越明显。这些结果归因于Al掺杂破坏了Mn离子之间的交换路径。
Polycrystalline samples YMn1-xAlxO3 with different Al doping concentration were synthesized by standard solid-state reaction. Effect of Al doping on the magnetic properties was studied. Magnetization measurements show that the magnetization increases, while the calculated frustration factor decreases with the doping content of Al3+ ion increasing. And the spin-glass behavior becomes more and more obvious with increasing the Al doping content. These results were ascribed to the broken exchange path between Mn ions by Al doping.
