| Abstract: | A mixed spin-1/2 and spin-3/2 transverse Ising model with random bond is studies within the framework of the finite cluster approximation (FCA).The phase diagrams and the other critical properties are examined.Re entrant phenomenon which comes from the frustration of exchange interaction is found. |
