N2 - By using a variational Monte Carlo technique, stability of the striped phases is studied for the two-dimensional t-J model with the three-site term near 1/8 hole doping. It is found that both diagonally and vertically striped phases are comparable in energy with the dx2-y2-wave superconducting state in the small-J/t region. Hole-'filled' domain walls prefer diagonal stripes, whereas 'half-filled' domain walls vertical ones, in accordance with the situation observed in nickelates and cuprates.
