Observation of Griffiths-like phase in Y2CrMnO6 perovskites

B-site disorder driven Griffiths-like phase and electrochemical behavior in Y2NiCrO6 double perovskite

“…The obtained λ value ~0.63 from the linear fit within the GP region clearly indicates the existence of GP in this perovskite. This finding is consistent with the similar value of λ (0.65) observed in the previously reported Y-based double perovskite Y 2 CrMnO 6 [23]. This large value of λ indicates that the Griffiths singularity is comparatively strong in this material due to the large amount of B-site cationic disordering [19].…”

“…In the temperature region of 400 K to 137 K, YNCO exhibits PM behavior. At a temperature of less than 137 K, the ZFC-FC magnetization curves clearly bifurcate due to the magnetic frustration within the YNCO material [23]. This frustration is a consequence of the mixed oxidation states of the transition metal cations, as confirmed by XPS analysis of the compound, leading to a complex and distinctive magnetic characteristic [23].…”

This frustration is a consequence of the mixed oxidation states of the transition metal cations, as confirmed by XPS analysis of the compound, leading to a complex and distinctive magnetic characteristic [23]. Interestingly, at the low-temperature region in the ZFC mode, we observed an unconventional negative magnetization which has also been reported in other double perovskite materials [13,14,78].…”

“…These characteristics make them appealing choices for enhancing device efficiency and functionality. In a number of previous investigations, structure-correlated electronic properties, competing magnetic interactions, emergence of GP, etc, were reported in Yttrium (Y)-based double perovskites [23][24][25]. Notably, Y-based parent single perovskites YNiO 3 and YCrO 3 that exhibited attractive magnetic properties for potential applications in spintronic, optoelectronic and energy storage devices motivated us to synthesize their double perovskite Y 2 NiCrO 6 (YNCO) [26,27].…”

“…Experimental investigations of GP have been conducted in various systems, including manganites [27][28][29], cobaltites [30,31], double perovskites [32,33], and several other materials [34,35]. GP originates from many different causes, such as structural disorder resulting from the introduction of dopant elements at different sites of the material [30,31], Jahn-Teller distortion [27][28][29], and grain size variation [27,28].…”
