T
he Fe-Mo based double perovskites have attracted much attention in the field of materials science due to their multiverse
fascinating physical properties which make them suitable candidates for several technological applications. In the present
work, the Sr
2-x
Nd
x
FeMoO
6
(0.0≤x≤0.3) samples have been investigated for their structural, magnetic and magnetocaloric
properties. Polycrystalline Sr
2-x

(0.0≤x≤0.3) samples were prepared by using the conventional solid-state reaction
method. To achieve the target double perovskite phase and to minimize the undesirable secondary phases, the samples were
sintered in a reducing atmosphere, created by a gas mixture of 5% H
2
/95% Ar. The structure, microstructure and phase
purity of the samples were investigated by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). XRD study
confirmed the formation of tetragonal structure with Fm3m space group in all the synthesized samples. The Arrott plots and
magnetization measurements showed a second order of ferromagnetic phase transition in all the fabricated samples. All the
samples went through a paramagnetic to ferromagnetic phase transition at the Curie temperature (TC). A magnetocaloric
effect was calculated in terms of isothermal magnetic entropy change. The value of the Relative Cooling Power (RCP) was
observed to decrease with the increasing Nd content. A significant variation in the magnetocaloric properties of the samples
was observed with the increasing Nd concentration. This investigation suggests that Sr

samples can be used as
potential magnetic refrigerants for magnetocaloric applications.
