A remarkable feature is that the magnetic correlation length along the orthorhombic $a\\rm_{ortho}$ axis is much longer than that along the $b\\rm_{ortho}$ 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 ($\\xi'_a\\sim160$ \\AA, $\\xi'_b\\sim25$ \\AA, and $\\xi'_c\\sim4.7$ \\AA at 1.6 K).
