We have established a magnetic phase diagram of (La1-zPr z)1.2Sr1.8Mn2O7 for z = 0.6 by means of magnetization measurements. The magnetization curve exhibits a rectangular hysteresis loop below T*, implying the ferromagnetic behavior. A metamagnetic transition was observed also above T* without a hysteresis. Combined with our previous data of the elastic constants, it was found that there were mainly three magnetic phases in the Field-Temperature (H-T) phase diagram. The magnetic properties of (La1-zPr z)1.2Sr1.8Mn2O7 for z = 0.6 at low temperatures is discussed in terms of spin- and orbital-glass state.
