摘要：

The spin spiral state in the t-J model is obtained in the Hartree-Fock approximation. It is proved to be unstable against spatial hole condensation into a ferromagnetic hole drop on the antiferromagnetic hole-less background. When J>4t the hole drop is shown to be the electron vacuum. The influence of the surface tension and Coulomb repulsion on the drop is discussed,
