This paper presents a study for the electronic and magnetic properties of Cd_1-xMn_xTe quantum wire (QW). The Hamiltonian for an electron confined in a quantum wire, in the presence of an external magnetic field and Rashba spin orbit interaction, had been solved. The obtained energy dispersion relation had been used to calculate the electronic structure and display the Landau levels and density of states for different physical Hamiltonian s parameters. The density of states function shows a significant dependence on spin, Rashba, exchange effect and magnetic field. The dependence of the magnetic properties like magnetization and magnetic susceptibility on the magnetic field strength, quantum wire radius, and exchange and Rashba strength parameters have been examined. The computed results show that the material can display a phase transition between Paramagnetic and Diamagnetic types. In addition, an oscillatory behavior in the magnetic susceptibility as a function of magnetic field has been observed. This oscillating behavior is a result of Landau levels crossing in the quantum wire energy spectra.
