Title:
Freezing of Anisotropic Spin Clusters in ${\mathrm{La}}_{1.98}{\mathrm{Sr}}_{0.02}{\mathrm{CuO}}_{4}$ 
Abstract:
A spin-glass compound, La1.98Sr0.02CuO4, shows quasi-three-dimensional magnetic ordering below $\sim$40K. A remarkable feature is that the magnetic correlation length along the orthorhombic aortho axis is much longer than that along the bortho axis, suggesting that the spin structure is closely related to the diagonal stripe structure. The spin-glass state can be expressed as a random freezing of quasi-three-dimensional spin clusters with anisotropic spin correlations ($\xi′$a$\sim$160\AA, $\xi′...    »
