Li3InBr6 and NaInBr4 have been synthesized and characterized by means of DTA, 8 'Br NQR, Li, Li, Na, and l l In NMR, and AC conductivity. These measurements revealed the presence of phase transitions and cationic diffusion in both compounds. From the spin-lattice relaxation times of 1 Br NQR and the peak widths of Li and Na NMR spectra, it is deduced that the conduction is due to cationic diffu...

NQR studies o f a number of molecular complexes with p-chloronitrobenzene and o-chloronitrobenzene as acceptors and different hydrocarbons as donors were carried out. A linear relationship between the NQR shift and the ionization potentials o f the donors is obtained. Maksyutin’s idea o f a positive shift with respect to acceptors having a quadrupolar nucleus is shown to hold in those systems. ...

La nuclear quadrupole resistance ~NQR! and relaxation measurements in lightly hole-doped La1.82xEu0.2SrxCuO4 have been used to investigate the microscopic properties of the low-temperature orthorhombic to low-temperature tetragonal transition. The transition is characterized by a sharp peak in La NQR relaxation rate, indicating phonon softening. We find that the structural phase transition is a...

We report $^{121/123}$Sb nuclear quadrupole resonance (NQR) and $^{51}$V magnetic (NMR) measurements on kagome metal CsV$_3$Sb$_5$ with $T_{\rm c}=2.5$ K. Both NMR spectra NQR split after a charge density wave (CDW) transition, which demonstrates commensurate CDW state. The coexistence of the high temperature phase between $91$ K $94$ manifests that it is first order transition. At low temperat...

Most ecological management applications use wireless sensor networks (WSNs) to collect data regularly, with great temporal redundancy. As a result, significant amount of energy is used transmitting redundant data, making it tremendously problematic attain satisfactory network lifetime, which bottleneck in enduring such environmental monitoring applications. A two-vector prediction model that ba...

Dynamic processes in solids exhibiting structurally incommensurate phases are briefly reviewed, and the application of NMR and NQR is discussed. The unique utility of these methods, arising due to, on one hand, the microscopic resonant nature of the probe used and, on the other, the presence of periodic, though incommensurable, structure , is brought out by presenting recent results in a protot...

We report experimental evidence for the spatial variation of hole concentration x(hole) in the high T(c) superconductor La2-xSrxCuO4 ( 0.04 < or = x < or = 0.16) via 63Cu NQR using 63Cu isotope enriched samples. We demonstrate that the extent of the spatial variation of the local hole concentration Delta(x)hole is reflected on (63)1/T1 and deduce the temperature dependence. Delta(x)hole increas...
