| Popis: | We present evidence of coexistence of electron paramagnetic resonance signal and antiferromagnetic resonance signals above the antiferromagnetic (AFM) transition $({T}_{N})$ in ${\mathrm{Pr}}_{0.5}{\mathrm{Ca}}_{0.5}{\mathrm{MnO}}_{3}$. We identify the latter with AFM rare regions within the ``Griffiths-like'' phase scenario with the associated temperature scale ${T}^{*}$ extending above room temperature. |
