Stabilization of crystal and magnetic structure of Gd2Al1-xInx

A random mixture of two compounds with different type of crystal structure and magnetic characteristic which can lead to a new phase, is studied to find out the critical point at which both of them stabilized. such an interesting random system can be found by; 1) Gd2Al with two different magnetic phase transition on which Tc is unstable 2) Gd2In which is also shows two magnetic phase transition, but completely different with Gd2Al on which TN is unstable. The stabilized point which is consider experimentally by X-Ray diffraction and theoretically by WIEN2K is suggested to be at x=0.3 where it is a good agreement between these two methods.
