摘要：
Obliquely propagating dust ion acoustic solitary waves subjected to an external magnetic field are studied using Sagdeev's pseudopotential technique. Nonthermal distribution for electrons is considered. The pseudopotential is derived without considering the quasineutrality condition. It is obtained from the Poisson equation instead. Using Sagdeev's technique, the ranges of parameters for which solitary waves exist are studied in detail.
