In this work we focus on the Sr0.6Ba0.4MnO3 composition grown on (LaAlO3)0.3(Sr2AlTaO6)0.7 substrate. The MW complex electromagnetic response shows a decrease in the real part and a clear anomaly in the imaginary part around 150 K. Moreover, it coincides with a 17% hardening of the lowest-frequency polar phonon seen in IR reflectance spectra. In order to further elucidate this phenomenon, low-energy muon-spin spectroscopy was carried out, signaling the emergence of antiferromagnetic order with Néel temperature (TN) around 150 K. Thus, our results confirm that epitaxial Sr0.6Ba0.4MnO3 thin films display strong spin-phonon coupling below TN, which may stimulate further research on tuning the magnetoelectric coupling by controlling the epitaxial strain and chemical pressure in the Sr1-xBaxMnO3 system. 000061838 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E26$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2014-51982-C2 000061838 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc$$uhttp://creativecommons.org/licenses/by-nc/3.0/es/ 000061838 590__ $$a3.813$$b2017 000061838 591__ $$aPHYSICS, CONDENSED MATTER$$b18 / 67 = 0.269$$c2017$$dQ2$$eT1 000061838 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000061838 700__ $$0(orcid)0000-0002-6944-4713$$aLangenberg, E. 000061838 700__ $$0(orcid)0000-0002-5331-9758$$aMarcano, N.$$uUniversidad de Zaragoza 000061838 700__ $$aBovtun, V. 000061838 700__ $$0(orcid)0000-0002-6487-1505$$aMaurel, L. 000061838 700__ $$aKempa, M. 000061838 700__ $$aProkscha, T. 000061838 700__ $$aKroupa, J. 000061838 700__ $$0(orcid)0000-0002-4698-3378$$aAlgarabel, P.A.$$uUniversidad de Zaragoza 000061838 700__ $$0(orcid)0000-0002-0111-8284$$aPardo, J.A.$$uUniversidad de Zaragoza 000061838 700__ $$aKamba, S. 000061838 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
