摘要:
通过水热法合成一系列不同掺杂浓度晶体[NH-2(CH-3)-2]Mn-1-x-Mgx(HCOO)3(0≤x≤0.5),并对其进行X射线粉末衍射、紫外可见光谱、傅里叶变化红外光谱(FTIR)、热重等表征分析。结果表明:制备晶体的结晶性能好,透明度高,晶体为三方晶系,空间群为R-3c(167);Mg-2+的掺入加剧了MnO6八面体的畸变,导致晶体的晶格参数发生明显变化;晶体结构框架在120 ℃时开始坍塌,在230 ℃时,甲酸根分解挥发。光学测试结果表明:晶体的禁带宽度为3.73 eV,Mg掺杂对禁带宽度没有影响。磁性测试结果表明:当测试温度范围为5~300 K时,随着掺杂量增加,样品的奈耳温度(T-N)变小,当掺杂量为0.5,反铁磁转变消失。
