摘要
We present evidence of coexistence of electron paramagnetic resonance signal and antiferromagnetic resonance signals above the antiferromagnetic (AFM) transition (T-N) in Pr0.5Ca0.5MnO3. We identify the latter with AFM rare regions within the "Griffiths-like" phase scenario with the associated temperature scale T* extending above room temperature.
