Magnetism of stripe-ordered La5/3Sr1/3NiO4
26 April 1999
La-139 nuclear magnetic resonance studies reveal markedly different magnetic properties of the two sites created by the charged domain wall formation in La5/3ST1/3NiO4 Nuclear magnetic resonance is slow compared to neutron scattering; we observe a 30 K suppression in magnetic ordering temperature indicating glassy behavior. Applied magnetic field reorients the in-plane ordered moments with respect to the lattice, but the relative orientation of the spins among themselves is stiff and broadly distributed.
