测量了单晶UPt 3与Al之间的Josephson临界电流Ic,测量了UPt 3面上垂直于a [11 2 0]和B [10 1 0]轴的角结。在磁场为零时,Ic的磁场依赖性显示出全局最大值,就像单面上的结一样。到目前为止,我们还没有观察到指示a轴和B轴方向之间的序参量的相移的行为。
Josephson critical current I c between a single crystal UPt 3 and Al has been measured for a corner junction on the UPt 3 faces perpendicular to the a [11 2 0] and b [10 1 0] axes. The magnetic field dependence of I c has shown a global maximum at zero magnetic field like the junctions on a single face. We have not observed a behavior indicating the phase shift of the order parameter between the a - and b -axis directions thus far.
