在分析重费米子超导体核自旋晶格弛豫时间测量的基础上，估算了低能下反铁磁波矢附近的动力学磁化率与温度的关系。发现的依赖关系和反铁磁关联长度与三维反铁磁自旋密度波不稳定性的量子临界行为是一致的。
Based on analysis of nuclearspin-lattice relaxation-time measurements on the heavy-fermion superconductor,,, and temperature dependences of the dynamical susceptibilitynear the antiferromagnetic wave vectorat low energyhave been estimated. Thedependences found,and antiferromagnetic correlation length, are consistent with quantum critical behavior for a three-dimensional antiferromagnethaving a spin-density-wave instability.
