Abstract

with x =0.036. Below 40 K a signal wipeout of As-75 NMR spectra is observed for the crystals with x =0.036 and 0.037. This fact together with spin-lattice relaxation peculiarities is treated a result of the system glassy behavior in this region of the phase diagram. The As-75 NMR data also indicate on partial suppression of antiferromagnetic spin fluctuations around the Ni impurity in these crystals at low temperatures.
