The present communication addresses the magnetoperistalsis of Jeffrey nanomaterial in a vertical asymmetric compliant channel walls. Flow modeling is based upon mixed convection, non-Darcy’s resistance, thermal radiation, Brownian motion and thermophoresis, chemical reaction and activation energy. Nonlinear thermal radiation is taken instead of classical linear radiation consideration. Buongiorno model is used for nanofluid analysis. Channel boundaries are associated with no-slip, compliant characteristics and convective heat and mass transfer effects. Lubrication approach is followed and problems are numerically solved. Quantities of interest are analyzed physically. It is observed that velocity enhances for Hall and Darcy parameters. Temperature decreases with radiation parameter. It is found that concentration increases by increasing activation energy parameter.
