Singlet Ground State of the Quantum Antiferromagnet Ba3CuSb2O9
J. A. Quilliam, F. Bert, E. Kermarrec +6
We present local probe results on the honeycomb lattice antiferromagnet Ba3CuSb2O9. Muon spin relaxation measurements in zero field down to 20 mK show unequivocally that there is a…
Spin dynamics, short range order and spin freezing in Y0.5Ca0.5BaCo4O7
J R Stewart, G Ehlers, H Mutka +3
Y0.5Ca0.5BaCo4O7 was recently introduced as a possible candidate for capturing some of the predicted classical spin kagome ground state features. Stimulated by this conjecture we h…
Unconventional antiferromagnetic correlations of the doped Haldane gap system YBaNiZnO
V. Villar, R. Mélin, C. Paulsen +3
We make a new proposal to describe the very low temperature susceptibility of the doped Haldane gap compound YBaNiZnO. We propose a new mean field model relevan…
Random interactions and spin-glass thermodynamic transition in the hole-doped Haldane system YCaBaNiO
E. Janod, C. Payen, F. -X. Lannuzel +1
Magnetization, DC and AC bulk susceptibility of the =1 Haldane chain system doped with electronic holes, YCaBaNiO (0x0.20), have been measured and an…
Evidence of quantum criticality in the doped Haldane system Y2BaNiO5
C. Payen, E. Janod, K. Schoumacker +3
Experimental bulk susceptibility X(T) and magnetization M(H,T) of the S=1-Haldane chain system doped with nonmagnetic impurities, Y2BaNi1-xZnxO5 (x=0.04,0.06,0.08), are analyzed. A…
