Evidence for a Griffiths Phase to Cluster Spin Glass Transition in the La_2/3Sr_1/3(Mn_1-3 _xAl₂ _xTi_x)O₃ System.

ABSTRACT: The presence of Griffiths phase to cluster spin glass transition has theoretically been predicted in both classical and quantum systems. However, its detection in a classical system has been lacking for decades, which hinders a complete understanding of the relationship between the Griffiths phase and cluster spin glass. Here, the experimental discovery of the Griffiths phase to cluster spin glass transition is reported in a classical magnetic system, diluted ferromagnets La_2/3Sr_1/3(Mn_{1-3 x}Al_{2 x}Ti_x)O₃ (0 ≤ x ≤ 0.12). The phase diagram of the system shows a transition from the Griffiths phase into a ferromagnetic state in the low disorder concentration range (0.01 < x ≤ 0.09). In the high disorder concen
