摘要：
The energy spectrum of Hubbard model with infinite repulsion on two types of distorted necklace ladder with additional diagonal interactions is studied analytically and numerically. For the diamond type lattice we demonstrate the appearance of magnetic polarons at negative ratio of hopping parameters describing the interactions of neighbor unit cells. For second type of the lattice, despite of similar triangular topology, the corresponding polarons have nonmagnetic character.
