Abstract

We have established a magnetic phase diagram of (La_1-zPr _z)_1.2Sr_1.8Mn₂O₇ 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 (La_1-zPr _z)_1.2Sr_1.8Mn₂O₇ for z = 0.6 at low temperatures is discussed in terms of spin- and orbital-glass state.
