Magnetic and magnetocaloric properties in TbCo2Si2 alloy

Herein, structural, magnetic and magnetocaloric properties of TbCo2Si2 polycrystalline alloy are investigated. From the temperature dependent magnetization curve, TbCo2Si2 alloy is found to undergo a second order antiferromagnetic to paramagnetic transition at Neel temperature (TN)=46 K. Magnetic entropy change (ΔSM) for the alloy is estimated in a broad temperature region of 5 K -150 K and a maximum value of ΔSM about 1.8 Jkg−1K-−1 with relative cooling power ∼ 42.84 J/kg is found across its TN due to a magnetic field changes of 5 T. The material will be useful for magnetic refrigeration technology.
