New structure type in the morphotropic series of A 2 + M 2 2+ (MoO4)3: crystal structure of Rb2Cu2(MoO4)3

Rb-NMR study of the quasi-one-dimensional competing spin-chain compound Rb2Cu2Mo3Matsui1, Yagi2, Hoshino3 et al. 2017Phys. Rev. B164150View full textAdd to dashboardCite

“…The title compound Rb 2 Cu 2 Mo 3 O 12 , the quasi-one dimensional quantum spin chain system, involves both of these two phenomena [1][2][3]. It consists of so-called ribbon-chains of = ½ spins, in which the ferromagnetic and antiferromagnetic exchange interactions work on the nearest neighboring and the next nearest neighboring spins, respectively.…”

Conversion method of powder inelastic scattering data for one-dimensional systems

“…1 We then used the treatment to extract the spin dispersion in another 1D spin-1/2 system, Rb 2 Cu 2 Mo 3 O 12 , a system where no large single crystals exist and the spin excitations have not so far been measured. 5 The powder inelastic neutron scattering data on CuGeO 3 and Rb 2 Cu 2 Mo 3 O 12 in this paper were measured on direct geometry time-of-flight chopper spectrometers, MARI installed at ISIS and LRMECS installed at IPNS, respectively. The energy of incident neutrons ͑E i ͒ was fixed at 45 and 15 meV, and the energy resolution ⌬E / E i was estimated to be about 2%-4% and 4%-8% for MARI and LRMECS, respectively.…”

Ground State of Quasi-One Dimensional Competing Spin Chain Cs2Cu2Mo3O12 at zero and Finite Fields

“…The ground state of the competing-spin chain R 2 Cu 2 Mo 3 O 12 [1,2] has attracted much interest, not only for the possibility of spin nematic state [3][4][5][6][7][8][9][10][11], but because the two isomorphic compounds with R= Cs and Rb show different ground states [11][12][13][14]. While the former shows a magnetic order at T N = 1.8 K, the latter shows a small spin gap of /k B = 1.6K.…”
