Based on the quantum states of an electron trapped on an infinite band along the x-axis in the presence of the Morse-like perpendicular magnetic field [H. Fakhri, B. Mojaveri, M.A. Gomshi Nobary, Rep. Math. Phys. 66, 299 (2010)], the Klauder-Perelomov and Gazeau-Klauder coherent states are constructed. To realize the resolution of identity, their corresponding positive definite measure on the complex plane are obtained in terms of the known functions. Also, some nonclassical properties such as sub-Poissonian statistics and squeezing effect of constructed coherent states are studied.
