Abstract
The renormalization-group theory of the d = 3 tJ model is extended to further-neighbor an-tiferromagnetic or electron-hopping interactions, including the ranges of frustration. The global phase diagram of each model is calculated for the entire ranges of temperatures, electron densities, further first-neighbor interaction-strength ratios. With the inclusion of further-neighbor interactions, an extremely rich phase diagram structure is found and is explained by competing and frustrated interactions. In addition to the ¿tJ phase seen in earlier studies of the nearest-neighbor d = 3tJ model, the ¿Hb phase seen before in the d = 3 Hubbard model appears both near and away from half-filling.
