摘要
We use the two fluid model to determine the conditions under which the nuclear spin-lattice lattice relaxation rate T-1 of candidate heavy 量子 critical superconductors can exhibit 縮放律 behavior and find that it can occur if and only if their "hidden" 量子 critical spin fluctuations give rise to a temperature-independent intrinsic heavy electron spin-lattice relaxation rate. The resulting 縮放律 of T-1 with the strength of the heavy electron component and the coherence temperature T* provides a simple test for their presence at pressures at which the superconducting transition temperature T-c is maximum and is proportional to T*. These findings support the previously noted partial 縮放律 of the spin-lattice relaxation rate with T-c in a number of important heavy electron materials and provide additio
