Dynamics of an anisotropic Haldane antiferromagnet in strong magnetic field
A. Zheludev, S. M. Shapiro, Z. Honda +8
We report the results of elastic and inelastic neutron scattering experiments on the Haldane gap quantum antiferromagnet Ni(C5D14N2)2N3(PF6) performed at mK temperatures in a wide…

Direct Observation of the Quantum Energy Gap in S = 1/2 Tetragonal Cuprate Antiferromagnets
K. Katsumata, M. Hagiwara, Z. Honda +9
Using an electron spin resonance spectrometer covering a wide range of frequency and magnetic field, we have measured the low energy excitations of the S=1/2 tetragonal antiferroma…
