“…18 However, below 100 K, the curves deviate entirely from the C−W law forming a paramagnetic-like tail with an intensity increase probably associated with the magnetic contribution provided by Gd 3+ ions. 82 Their linear fittings yield positive Θ Weiss values of 42 K (50 Oe), 51 K (500 Oe), and 49 K (5 kOe), which indicates the predominance FM/FiM interactions above T C . We also observed that the frustration factor, defined as f frus = |Θ Weiss |/T C , 83 yields f frus = 0.65, 0.78, and 0.75, respectively.…”

“…Many oxides containing rare-earths and transition metals have been found to be showing good MCE [4]. In this context rare-earth transition metal perovskites of the form ABO 3 (where A is the rare-earth ion and B is the transition metal ion) which show magnetic transition at low T are interesting for investigation of low T MCE [7][8][9][10][11][12]. In last few years, a new family of mixed metal oxides (combining orthoferrites and orthochromites) of the form RFe 0.5 Cr 0.5 O 3 , is discovered in perovskites and are being extensively investigated [13][14][15][16][17][18].…”

“…Among the topical magnetism studies, the magnetocaloric effect (MCE) has drawn a great deal of interest due of their potential application as a magnetic refrigerant material. [25][26][27][28] The extent of MCE depends on three major metal-specific features: (i) large spin ground state, (ii) the zero orbital momentum and (c) the weak super-exchange interactions. [29][30][31][32][33] Taking cue from this, we envisioned that the cryogenic magnetic cooling behaviour of a Fe 3 + based metallogel with least periodic microstructure perfectly suit the purpose.…”
