The downward deviation in the inverse low-field dc susceptibility ¿dc-1 from the Curie-Weiss law below a characteristic temperature TG indicates that the Griffiths-like phase exists at pressures up to 10 kbar. From the obtained T-P phase diagrams, the pressure coefficient of the Griffiths-like temperature, dTG/dP, has been determined. These results are compared with those obtained in Dy5Si3Ge in a previous work. The dTG/dP coefficient is strongly dependent on the nature (first or second order) of the long-range order (FM or AFM) transition. This effect can be ascribed to a different structural character of the clusters within the Griffiths phase. A ratio of ~0.5 between the dTG/dP and the pressure coefficient of long-range magnetic ordering temperatures, dTC, N/dP (TC, ferromagnetic; TN, antiferromagnetic), is found in all the studied compounds. 000097108 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E28-20R$$9info:eu-repo/grantAgreement/ES/MCIU/MAT2017-82970-C2-2-R 000097108 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000097108 590__ $$a4.036$$b2020 000097108 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b130 / 333 = 0.39$$c2020$$dQ2$$eT2 000097108 591__ $$aPHYSICS, CONDENSED MATTER$$b22 / 69 = 0.319$$c2020$$dQ2$$eT1 000097108 591__ $$aPHYSICS, APPLIED$$b41 / 160 = 0.256$$c2020$$dQ2$$eT1 000097108 592__ $$a1.78$$b2020 000097108 593__ $$aElectronic, Optical and Magnetic Materials$$c2020$$dQ1 000097108 593__ $$aCondensed Matter Physics$$c2020$$dQ1 000097108 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000097108 700__ $$0(orcid)0000-0002-4698-3378$$aAlgarabel, P.A.$$uUniversidad de Zaragoza 000097108 700__ $$aFernández, J.R. 000097108 700__ $$aAraujo, J.P. 000097108 700__ $$aPereira, A.M. 000097108 700__ $$aBelo, J.H. 000097108 700__ $$0(orcid)0000-0002-6761-6171$$aMagén, C.$$uUniversidad de Zaragoza 000097108 700__ $$0(orcid)0000-0003-3724-508X$$aMorellón, L.$$uUniversidad de Zaragoza 000097108 700__ $$0(orcid)0000-0003-0681-8260$$aIbarra, M.R.$$uUniversidad de Zaragoza 000097108 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
