Abstract

We present evidence of coexistence of electron paramagnetic resonance signal and antiferromagnetic resonance signals above the antiferromagnetic (AFM) transition (T_N) in Pr_0.5Ca_0.5MnO₃. We identify the latter with AFM rare regions within the ``Griffiths-like'' phase scenario with the associated temperature scale T^* extending above room temperature.
