Spin glass behavior in frustrated quantum spin system CuAl2O4 with a possible orbital liquid state
R. Nirmala, Kwang-Hyun Jang, Hasung Sim +10
CuAl2O4 is a normal spinel oxide having quantum spin, S=1/2 for Cu2+. It is a rather unique feature that the Cu2+ ions of CuAl2O4 sit at a tetrahedral position, not like the usual…
Complex Spin Structures and Origin of the Magneto-Electric Coupling in YMn2O5
J. -H. Kim, S. -H. Lee, S. I. Park +12
By combining neutron four-circle diffraction and polarized neutron diffraction techniques we have determined the complex spin structures of a multiferroic, YMn2O5, that exhibits tw…
Frustrated minority spins in GeNi2O4
M. Matsuda, J. -H. Chung, S. Park +10
Recently, two consecutive phase transitions were observed, upon cooling, in an antiferromagnetic spinel GeNiO at K and K, respectively \cite{mat…
Statics and dynamics of an incommensurate spin order in a geometrically frustrated antiferromagnet CdCrO
J. -H. Chung, M. Matsuda, S. -H. Lee +6
Using elastic and inelastic neutron scattering we show that a cubic spinel, CdCrO, undergoes an elongation along the c-axis () at its spin-Peierls-like phase tra…
