  Although La(2)Cu(1-x)Li(x)O(4) [Li-LCO] differs from La(2-x)Sr(x)CuO(4)
[Sr-LCO] in many ways (e.g., the absence of metallic transport, high-Tc
superconductivity, and incommensurate antiferromagnetic correlations), it has
been known that certain magnetic properties are remarkably similar. The present
work establishes the detailed bulk magnetic phase diagram of Li-LCO (0 <= x <=
0.07), which is found to be nearly identical to that of lightly-doped Sr-LCO,
and therefore extends the universality of the phase diagram to hole-doped but
nonsuperconducting cuprates.
