Figure 7
Temperature variation of the resistance as measured at zero field.
With dc current I parallel to the <001> axis (up) and along the <110> zone (down). We note that the threshold of magnetic field for weakening the SDW state is so small (Fig. 5) that the commercial PPMS is unable to detect the potential weak magnetoresistance effect. The SDW state observed here represents more or less a new type of spin state since its threshold field is extremely small. Therefore, we propose that ErPd2Si2 is a SDW conductor.
