Magnetic excitations from the hexagonal spin clusters in the S = 1/2 distorted honeycomb lattice antiferromagnet Cu2(pymca)3(ClO4)
Masaaki Matsuda, Alexander I. Kolesnikov, Zentaro Honda +4
Cu2(pymca)3(ClO4) (pymca: pyrimidine-2-carboxylate) consists of a slightly distorted honeycomb lattice of Cu2+ spins, which shows no long-range magnetic order down to 0.6 K. A magn…
Vacancy-induced suppression of CDW order and its impact on magnetic order in kagome antiferromagnet FeGe
Mason L. Klemm, Saif Siddique, Yuan-Chun Chang +16
Two-dimensional (2D) kagome lattice metals are interesting because they display flat electronic bands, Dirac points, Van Hove singularities, and can have interplay between charge d…
Frustrated magnetic interactions in an S=3/2 bilayer honeycomb lattice compound Bi3Mn4O12(NO3)
M. Matsuda, S. E. Dissanayake, D. L. Abernathy +4
Inelastic neutron scattering study has been performed in an S=3/2 bilayer honeycomb lattice compound Bi3Mn4O12(NO3) at ambient and high magnetic fields. Relatively broad and monoto…
Structural and Magnetic Phase Transitions in CeCu ( = Ag, Pd)
L. Poudel, C. de la Cruz, E. A. Payzant +18
The structural and the magnetic properties of CeCuAg (0 0.85) and CeCuPd (0 0.4) have been studied using neutron diffrac…
Magnetic excitations from an S=1/2 diamond-shaped tetramer compound Cu2PO4OH
M. Matsuda, S. E. Dissanayake, D. L. Abernathy +2
Inelastic neutron scattering experiments have been carried out on a powder sample of Cu2PO4OH, which consists of diamond-shaped tetramer spin units with S=1/2. We have observed two…
Magnetic ordering induced by interladder coupling in the spin-1/2 Heisenberg two-leg ladder antiferromagnet CHNCuBr
Tao Hong, K. P. Schmidt, K. Coester +14
We present specific-heat and neutron-scattering results for the \emph{S}=1/2 quantum antiferromagnet (dimethylammonium)(3,5-dimethylpyridinium)CuBr. The material orders magneti…
Magnetic and Structural Phase Transitions in the Spinel Compound Fe1+xCr2-xO4
J. Ma, V. O. Garlea, A. Rondinone +10
Neutron and X-ray diffraction, magnetic susceptibility, and specific heat measurements have been used to investigate the magnetic and structural phase transitions of the spinel sys…
Magnetic Phase Transition in the Low Dimensional Compound BaMn2Si2O7
J. Ma, C. D. Dela Cruz, T. Hong +7
The structural and magnetic properties of BaMn2Si2O7 have been investigated. The magnetic susceptibility and specific heat, measured using single crystals, suggest that the quasi-o…
Incommensurate dynamic correlations in the quasi-two-dimensional spin liquid BiCu2PO6
K. W. Plumb, Zahra Yamani, M. Matsuda +4
We report detailed inelastic neutron scattering measurements on single crystals of the frustrated two-leg ladder BiCu2PO6, whose ground state is described as a spin liquid phase wi…
Magnetic dispersion and anisotropy in multiferroic BiFeO3
M. Matsuda, R. S. Fishman, T. Hong +5
We have determined the full magnetic dispersion relations of multiferroic BiFeO3. In particular, two excitation gaps originating from magnetic anisotropies have been clearly observ…
Partially disordered state and spin-lattice coupling in an S=3/2 triangular lattice antiferromagnet Ag2CrO2
M. Matsuda, H. Yoshida, M. Isobe +2
Ag2CrO2 is an S=3/2 frustrated triangular lattice antiferromagnet without orbital degree of freedom. With decreasing temperature, a 4-sublatice spin state develops. However, a long…
