Nb_3Te_4单晶输运性质及磁化率测量

Measurements of the Transport and the Magnetic Susceptibility of Nb_3Te_4 Single Crystal

测量了Nb3Te4单晶在不同磁场及电场作用下R（T）/（300K）～T曲线，发现磁场对高温Peierls相变温度的回滞有“压缩”作用，电场对高温Peierls相变温度的回滞有“加宽”作用．另外，测量磁化率时还发现，T＜50K时，晶体出现抗磁信号．

The temperature dependence of the normalized resistance of Nb3Te4 single crystal was measured finder different magnetic fields and different electric fields around T1=100K. It was found that magnetic fieldssuppress the kystercsis of the phase transition temperature, and electric fields broaden tile hysteresis. Thetemperature dependence of the magnetic susceptibility of Nb3Te4 single crystal showed that antimagnetiesignal occurs below T2=50K.
