Abstract
The effects of Eu 3+ doping on the structural and magnetocaloric effect of Ruddlesden-Popper compounds La 1.4-xEu xSr 1.6Mn 2O 7 (0 ≤ x ≤ 0.1) were investigated. The X-ray diffraction and infrared spectroscopy confirmed that La 1.4-xEu xSr 1.6Mn 2O 7 compounds exhibited the tetragonal lattice symmetry (I4/mmm) of the Ruddlesden-Popper phase. The crystal structure of La 1.4-xEu xSr 1.6Mn 2O 7 compounds distorted and phase separated as the amount of Eu 3+ doping varied. The magnetization-temperature curves demonstrated that La 1.4-xEu xSr 1.6Mn 2O 7 compounds display a notable transition temperature attributed to its anisotropic exchange coupling. The maximum magnetic entropy changes ( − Δ S M max ) of La 1.4-xEu xSr 1.6Mn 2O 7( x = 0, 0.075, and 0.1) compounds are 2.82, 3.12 and 3.40 J/(kg·K) at the 5 T applied magnetic field. Meanwhile, its relative cooling power ( RCP) was 186.37, 207.42 and 242.54 J/kg, respectively. The critical behavior of La 1.4-xEu xSr 1.6Mn 2O 7 (0≤ x≤0.1) compounds was analyzed around Tc, and it was found that the critical index (β = 0.413, γ = 1.020, δ = 3.038) is essentially in line with the mean field theory.
