La139 NMR investigation of the interplay between lattice, charge, and spin dynamics in the charge-ordered high-Tc cuprate La1.875Ba0.125CuO4

We investigate the interplay between the lattice, charge, and spin dynamics in charge-ordered high Tc cuprate La1.875Ba0.125CuO4(Tc=4K) based on the inverse Laplace transform (ILT) analysis of the La139 nuclear spin-lattice relaxation rate 1/T1 (dubbed ILTT1 analysis hereafter). A major thrust of the ILTT1 analysis is that one can deduce the probability density function P(1/T1) of distributed 1/T1. We demonstrate that 1/T1lm, defined as the log …
