摘要:

当用小角中子散射研究时,由于235U裂变,UPt3中的涡旋晶格(VL)经历了作为时间的函数的逐渐无序。这将样品的区域暂时加热到高于临界温度,其中,在再冷却时,涡旋保持在淬灭的涡旋玻璃态。无序速率与磁场成正比,表明它是由集体VL属性,如弹性模量。一个有序的VL可以通过施加一个小的场振荡重新形成,表明裂变不会造成显着的辐射损伤的UPt3晶体,即使在长时间暴露。

英文摘要:

When studied by small-angle neutron scattering the vortex lattice (VL) in UPt3 undergoes a gradual disordering as a function of time due to 235U fission. This temporarily heats regions of the sample above the critical temperature, where, upon re-cooling, the vortices remain in a quenched vortex glass state. The disordering rate is proportional to the magnetic field, suggesting that it is governed by collective VL properties such as the elastic moduli. An ordered VL can be re-formed by applying a small field oscillation, showing that the fission does not cause significant radiation damage to the UPt3 crystals, even after long exposure.
