**Abstract**

Primary aim of current attempt is to analyze the peristaltic flow of non-Newtonian material in a curved channel subject to two salient features namely the Soret and Dufour and radial magnetic field. Channel walls are of compliant characteristics. Problem formulations for constitutive equations of Jeffrey fluid are made. Lubrication approach is implemented for the simplification of mathematical analysis. Dimensionless problems of stream function, temperature and concentration are computed numerically. Characteristics of distinct variables on the velocity, temperature, coefficient of heat transfer and concentration are examined. Besides this graphical results indicates that velocity profile enhances significantly for compliant wall parameters however due to the resistance characteristics of Lorentz force velocity profile decays. Furthermore it is noted that temperature profile enhances for larger Dufour number however reverse behavior is noticed in the concentration profile when Soret and Schmidt numbers are increased.
