摘要
人工合成了((Cu_(1-x)Mg_(x))_(3)B_(2)O_(6)样品,并且用浮区法生长单晶。掺杂浓度x选择为0、0.01、0.02和0.04。为了研究系统Cu_(3)B_(2)O_(6)的基态,测试了0.5 T磁场下材料((Cu_(1-x)Mg_(x))_(3)B_(2)O_(6)的磁化率。实验结果表明:随着掺杂浓度x的提升,系统的反铁磁序逐渐被破坏。比较了Mg掺杂和以前文献中Zn掺杂的物理效应的异同。
We synthesized the powder samples of((Cu_(1-x)Mg_(x))_(3)B_(2)O_(6) and grew the single crystals by floating-zone method.The different doping level x is chosen as x=0,0.01,0.02 and 0.04.The magnetic susceptibility of the samples in a magnetic field of 0.5 T was measured in order to reveal the ground state of Cu_(3)B_(2)O_(6).The experimental results show that as the doping level x increases,the antiferromagnetic order in the system is gradually destroyed.We also compared the physical effects of Mg-substitution with those of Zn-substitution in the previous literature.
