The disorder in any system affects their physical behaviour. In this scenario, we report the possibility of disorder in A2BB'O6 oxides and their effect on different magnetic properties. These systems show anti-site disorder by interchanging B and B' elements from their ordered position and giving rise to anti-phase boundary. The presence of disorder leads to a reduction in saturation magnetization and magnetic transition temperature. The disorder prevents the system from sharp magnetic transition which originates short-range clustered phase (or Griffiths phase) in the paramagnetic region just above the long-range magnetic transition temperature. Further, we report that the presence of anti-site disorder and anti-phase boundary, A2BB'O6 oxides give different interesting magnetic phases like metamagnetic transition, spin-glass, exchange bias, magnetocaloric effect, magnetodielectric, magnetoresistance, spin-phonon coupling, etc.

“…talline, single crystal, and thin film forms [2,6,7,10,12,15,[46][47][48][49][50][51][52]. The use of smaller rare-earth atoms (such as Gd, Ho) at the R site gives giant magnetocaloric effect [2,10,54]. It is evident that the compounds with a B-Mn combination of Ni-Mn and Co-Mn possess the higher − S M .…”

The magnetism and magnetocaloric effect in double perovskites is an alluring area of research due to its tunable nature. In particular, the exchange interactions and local ordering of magnetic sublattices are sensitive to the chemical substitution, synthesis/growth conditions, and strain. Here we study the effect of strain on magnetism in Gd 2 NiMnO 6 double perovskite thin films grown using pulsed laser deposition on SrTiO 3 (001) substrate. Magnetostructural study finds tensile strain to be the origin of perpendicular magnetic anisotropy in Gd 2 NiMnO 6 . Further, the anisotropic nature prevails in magnetocaloric effect as well. Magnetic entropy change along the in-plane direction is observed to be 21.82 J Kg −1 K −1 , which reduces to 9.84 J Kg −1 K −1 along the out-of-plane direction. Our theoretical calculation reveals a ferrimagnetic ground state of Gd 2 NiMnO 6 . The relative spin orientation of Ni and Mn changes from parallel configuration for strained Gd 2 NiMnO 6 to antiparallel configuration for strain-relaxed Gd 2 NiMnO 6 .

“… 35 The transition temperature and magnetocaloric effect can be enhanced by substituting non-magnetic Ti 3+ ion in Gd 2 CoMnTiO 6 compound by Zheng et al 36 It was found that MCE enhanced from 16.64 J kg −1 K −1 to 27.16 J kg −1 K −1 under Δ H = 6 T at cryogenic temperature. Patra et al 37 reported the synthesis of Ho 2 CoMnO 6 nanorod by using hydrothermal route and magnetocaloric effect gives a change in entropy value of 12.4 J kg −1 K −1 at low temperature for 7 T.…”
