This paper applies new phi(6) model expansion scheme to obtain solitons in magneto-optic waveguides that come with dual-power law nonlinearity. Initially, the solutions are in terms of Jacobi's elliptic functions. Upon approaching the limiting values of the modulus of ellipticity, bright, dark and singular solitons emerge. The existence criteria of such solitons are also presented. (C) 2020 Elsevier B.V. All rights reserved.
