摘要:

本文测量了在高达60 T的强磁场和1.4 ~ 40 K温度下的URu_2Si_2单晶的磁电阻率RHOxx。已经研究了磁场的不同取向,允许遵循所有磁相变和交叉对Q的依赖性,其中Q是磁场和易磁化轴c之间的角度。我们发现,所有的磁过渡和交叉遵循一个简单的1/cos(Q)定律,表明它们是由磁场在c轴上的投影控制。

英文摘要:

We present measurements of the magnetoresistivity RHOxx of URu2Si2 single crystals in high magnetic fields up to 60 T and at temperatures from 1.4 K to 40 K. Different orientations of the magnetic field have been investigated permitting to follow the dependence on Q of all magnetic phase transitions and crossovers, where Q is the angle between the magnetic field and the easy-axis c. We find out that all magnetic transitions and crossovers follow a simple 1/cos(Q) -law, indicating that they are controlled by the projection of the field on the c-axis.
