“…4. At the field 4.38 T, a critical divergence in 1 1 ⁄ [17] and an abrupt increase in the line width took place at the same temperature 1.8 K. This clearly demonstrates the existence of long range magnetic order, which is consistent with our previous report [9]. This finite N in the quasi-one dimensional system is considered to be brought by a weak inter chain interaction.…”

“…The NMR spectra were obtained by plotting the spin-echo amplitude against the applied field. The nuclear spin-lattice relaxation rate was obtained by tracing the spin-echo amplitude against the repetition rate of measurement [23][24][25][26][27][28].…”

Rb-NMR study has been performed on the quasi-one dimensional competing spin chain Rb 2 Cu 2 Mo 3 O 12 with ferromagnetic and antiferromagnetic exchange interactions on nearest neighboring and next nearest neighboring spins, respectively. The system changes from a gapped ground state at zero field to the gapless state at C ≃ 2 T, where the existence of magnetic order below 1 K was demonstrated by a broadening of NMR spectrum, associated with a critical divergence of 1 1 ⁄ . In higher temperature region, 1 −1 showed a power-law type temperature dependence, from which the field dependence of Luttinger parameter K was obtained and compared with theoretical calculations based on the spin nematic Tomonaga Luttinger Liquid (TLL) state.

“…Their temperature dependence is shown in Fig. 6., where H and H scaled well with the uniform susceptibility, giving the hyperfine coupling constants of the isotropic part A iso and anisotropic part 3A an to be 100 and 600 Oe/ B , respectively [12,13]. These moderately large values assure that the 1 H-NMR well probes the magnetization of the entire system.…”

“…The 1 H-NMR spectra were obtained in the temperature range between 1.8 and 300 K either by Fourier-transform of Free-induction decay (FID) signal, or plotting the spinecho amplitude against the applied field [13]. Figure 2 shows the temperature dependence of the uniform susceptibility of Ru0/B0/GNP, from which the background of the wrapping film (inset) was subtracted.…”

Low-Temperature Magnetism of Gold Nano Particles Contained in Electrochemical Sugar Recognition System

Low temperature magnetic properties were investigated on the gold nano particles (GNP) with an average size of 11.5 nm, assembled with molecules of ruthenium complex (Ru0) and phenylboronic acid (B0) by the proton nuclear resonance ( 1 H-NMR) and susceptibility measurements. The temperature dependence of the NMR shift and the uniform susceptibility was described as the sum of the Curie-Weiss term and a positive constant term. From the former, the average number of Ru0 on each GNP was estimated to be 118, which is 23 % of the calculation. The finite positive constant term shows a clear contrast with the well-known fact that the bulk gold is diamagnetic. Finally, a disappearance of the motional narrowing effect in the proton NMR spectra below 60 K indicates that the wavering motion of Ru0 complexes on GNP at room temperature is frozen at low temperatures.
