Abstract	Obliquely propagating exact localized nonlinear dust-acoustic waves are investigated in a hot magnetized two-ion-temperature dusty plasma consisting of a negatively charged, extremely massive, hot dust fluid and ions of two different temperatures. The reductive perturbation method has been employed to derive the Korteweg-de Vries (K-dV) equation which admits a solitary wave solution for small but finite amplitude limit. It has been shown that the presence of a second component of ions modifies the nature of dust-acoustic solitary structures and may excite solitary dust-acoustic holes (solitary waves with density dip) in such a dusty plasma system. Under certain conditions, holes (solitary waves with density dip) are more favourable than positive (density) solitons (solitary waves with density hump). The effects of dust fluid temperature, obliqueness, and external magnetic field on the properties of these dust-acoustic solitary structures are also briefly discussed.
