Single crystalline EuTiO3 shows antiferromagnetic ordering due to Eu2+ magnetic moments below TN=5.6K. This compound shows a giant magnetocaloric effect around its Néel temperature. The isothermal magnetic entropy change is 49Jkg-1K-1, the adiabatic temperature change is 21 K, and the refrigeration capacity is 500Jkg-1 for a field change of 7 T at TN. The single crystal and polycrystalline samples show similar values of the magnetic entropy and adiabatic temperature changes. The large magnetocaloric effect is due to suppression of the spin entropy associated with the localized 4f moment of Eu2+ ions. The giant magnetocaloric effect, together with negligible hysteresis, suggest that EuTiO3 could be a potential material for magnetic refrigeration below 40 K. 000048686 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/MAT2012-38318-C03-01 000048686 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000048686 590__ $$a3.836$$b2016 000048686 591__ $$aPHYSICS, CONDENSED MATTER$$b18 / 67 = 0.269$$c2016$$dQ2$$eT1 000048686 592__ $$a2.339$$b2016 000048686 593__ $$aElectronic, Optical and Magnetic Materials$$c2016$$dQ1 000048686 593__ $$aCondensed Matter Physics$$c2016$$dQ1 000048686 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000048686 700__ $$aMandal, P. 000048686 700__ $$aRubi, K. 000048686 700__ $$aChen, R. 000048686 700__ $$aWang, J.S. 000048686 700__ $$aMahendiran, R. 000048686 700__ $$0(orcid)0000-0002-4078-6808$$aLorusso, G. 000048686 700__ $$0(orcid)0000-0002-8028-9064$$aEvangelisti, M.$$uUniversidad de Zaragoza 000048686 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
