| Abstract: | The phase transitions and spontaneous magnetization properties of Anisotropy dilution and random bond Blurne-Capel Model (BCM) have been studied within the framework of an effective field theory. The effect of the random bond and anisotropy dilution on the phase diagrams is discussed. The trajectory of the tricritical point (TCP) in the phase space as a function of two different disorder parameters is presented. The phase diagrams and the curve of spontaneous magnetization are presented. |
