The Griffiths like phase embedded into paramagnetic matrix of mixed valence orthorhombic nanocrystalline manganite La0.50Ca0.50MnO3 is experimentally studied by means of sensitive magnetic susceptibility and electron spin resonance. A comparative study of the nano- and polycrystalline manganites indicates the temperature interval of the Griffiths like phase located above the Curie temperature of nanocrystalline one. The upper temperature limit for an existence of Griffiths like phase, revealed by the sensitive electron spin resonance, is 10 K higher than that of the magnetic susceptibility. This proves that the high frequency field is able to excite the relatively smaller magnetic clusters. © 2016 Elsevier B.V. All rights reserved.
