The characteristics of linear and nonlinear waves of ion temperature gradient mode in nonuniform electron-positron-ion magnetized plasma are investigated. A modified linear dispersion relation and its reduction in various limits are discussed. In nonlinear regime, ion temperature gradient mode–driven solitary and shock wave structures are obtained and discussed. It is found that corresponding peak potential and width of these nonlinear structures strongly depend on the positron number density and temperature. Our study reveals that in electron-positron-ion plasma, the ion energy transportation in laboratory as well as in astrophysical plasmas can be affected because of positrons.
