摘要:
Fermi–liquid theory in two dimensions, for electron or hole liquids flowing through antiferromagnetic assemblies, yieldsRT1αT, whereRis the electrical resistivity andT1−1the nuclear relaxation rate. This relation holds over an appropriate temperature range for Cu spins in underdoped high Tccuprates. Here a non–Fermi–liquid phase of a strongly disordered metallic spin glass is pointed out to exhibit a relationRT1∝Tn, again over a restricted temperature range, where the exponentnhas the meanfield value of 5/4.
