The deformation properties of the low-lying magnetic dipole excitations, known as scissors mode, are systematically studied within the framework of the generalized coherent state model. The present description is shown to be closely related to other interacting boson approaches as well as to the geometrical two-rotor model. The results are in good agreement with experiments and consistent with those obtained in other phenomenological as well as microscopic approaches.
