Magnetic properties of the Haldane-gap material [Ni(C₂H₈N₂)₂NO₂](BF₄)

Results of magnetization and high-field electron spin resonance (ESR) studies of the new spin-1 Haldane-chain material [Ni(C2H8N2)2NO2] (BF4) (NENB) are reported. A definite signature of the Haldane state in NENB was obtained. From the analysis of the frequency–field dependence of magnetic excitations in NENB, the spin-Hamiltonian parameters were calculated, yielding 1/kB = 17.4 K, g‖ = 2.14, D...

Psychophysical Measures of Two-tone Suppression and Distortion Products (2f₁-f₂) and (f₂-f₁)

Psychophysical two-tone suppression and the growth of the (2f• --f2} and • --f•) distortion products were measured in four normal-hearing young adults using a forward-masking paradigm. The stimulus parameters investigated were: (1)f• = 750 and 3000 Hz; (2)f2/f• = 1.1 l, 1.26, and 1.41; (3) L• = 50, 65, 80, and 90 dB SPL; and (4) L2 -L• varied from -20 to + 20 dB in 10-dB increments. It appears ...

Synthesis and Characterization of Tb[N(CN)₂]₃·2H₂O and Eu[N(CN)₂]₃·2H₂O: Two New Luminescent Rare-Earth Dicyanamides

Two new rare-earth dicyanamides, namely, Tb[N(CN)2]3‚2H2O and Eu[N(CN)2]3‚2H2O, have been prepared by ion exchange in aqueous solution, followed by evaporation of the solvent at room temperature. The structures of both compounds have been solved and refined from single-crystal and powder X-ray diffraction data, respectively. The two compounds are isostructural and are built up from irregular qu...
