Saitovitch and CBPF for experimental facilities.The IrMn/Py/Ru/Co (Py = Ni81Fe19) spin valves have been produced by sputtering deposition and analyzed by magnetization measurements and a theoretical modelling of their exchange interactions, based on the macro-spin model. The Ru thickness was grown between 6 and 22 Å, which is small enough to promote strong indirect coupling between Py and Co. Results of measurements showed a large and gradual change in the shape of hysteresis loops when the Ru thickness was varied. The theoretical analysis, using numerical calculations based on the gradient conjugate method, provides the exchange coupling constants (bilinear and biquadratic), the exchange anisotropy fields and the magnetic anisotropy fields (uniaxial and rotatable). The exchange bias fields of spin valves were compared to that of a IrMn/Py bilayer. We found that the difference between these fields oscillates with Ru thickness in the same manner as the bilinear coupling constants.Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica - ConcytecengElsevier B.V.Journal of Magnetism and Magnetic Materialsinfo:eu-repo/semantics/openAccessTheoretical modellingAnisotropy-1Binary alloys-1Conjugate gradient method-1Exchange coupling-1Ferrimagnetic materials-1Iridium alloys-1Iron alloys-1Magnetic anisotropy-1Magnetic devices-1Magnetic materials-1Magnetoresistance-1Manganese alloys-1Nickel alloys-1Numerical methods-1Exchange coupling constants-1Exchange-bias fields-1Magnetic anisotropy field-1Magnetization measurements-1Numerical calculation-1Spin valve-1Sputtering deposition-1Cobalt alloys-1https://purl.org/pe-repo/ocde/ford#1.03.00-1Effect of the strong coupling on the exchange bias field in IrMn/Py/Ru/Co spin valvesinfo:eu-repo/semantics/articlereponame:CONCYTEC-Institucionalinstname:Consejo Nacional de Ciencia Tecnología e Innovacióninstacron:CONCYTEC#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#20.500.12390/584oai:repositorio.concytec.gob.pe:20.500.12390/5842024-05-30 15:22:16.228http://purl.org/coar/access_right/c_14cbinfo:eu-repo/semantics/closedAccessmetadata only accesshttps://repositorio.concytec.gob.peRepositorio Institucional CONCYTECrepositorio@concytec.gob.pe#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#<Publication xmlns="https://www.openaire.eu/cerif-profile/1.1/" id="1ada6221-8365-4a1f-9df9-c7f2cfc9b703"> <Type xmlns="https://www.openaire.eu/cerif-profile/vocab/COAR_Publication_Types">http://purl.org/coar/resource_type/c_1843</Type> <Language>eng</Language> <Title>Effect of the strong coupling on the exchange bias field in IrMn/Py/Ru/Co spin valves</Title> <PublishedIn> <Publication> <Title>Journal of Magnetism and Magnetic Materials</Title> </Publication> </PublishedIn> <PublicationDate>2018</PublicationDate> <DOI>https://doi.org/10.1016/j.jmmm.2017.09.004</DOI> <SCP-Number>2-s2.0-85028995952</SCP-Number> <Authors> <Author> <DisplayName>Tarazona H.S.</DisplayName> <Person id="rp00839" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Alayo W.</DisplayName> <Person id="rp01111" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Landauro C.V.</DisplayName> <Person id="rp00840" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Quispe-Marcatoma J.</DisplayName> <Person id="rp01110" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> </Authors> <Editors> </Editors> <Publishers> <Publisher> <DisplayName>Elsevier B.V.</DisplayName> <OrgUnit /> </Publisher> </Publishers> <Keyword>Theoretical modelling</Keyword> <Keyword>Anisotropy</Keyword> <Keyword>Binary alloys</Keyword> <Keyword>Conjugate gradient method</Keyword> <Keyword>Exchange coupling</Keyword> <Keyword>Ferrimagnetic materials</Keyword> <Keyword>Iridium alloys</Keyword> <Keyword>Iron alloys</Keyword> <Keyword>Magnetic anisotropy</Keyword> <Keyword>Magnetic devices</Keyword> <Keyword>Magnetic materials</Keyword> <Keyword>Magnetoresistance</Keyword> <Keyword>Manganese alloys</Keyword> <Keyword>Nickel alloys</Keyword> <Keyword>Numerical methods</Keyword> <Keyword>Exchange coupling constants</Keyword> <Keyword>Exchange-bias fields</Keyword> <Keyword>Magnetic anisotropy field</Keyword> <Keyword>Magnetization measurements</Keyword> <Keyword>Numerical calculation</Keyword> <Keyword>Spin valve</Keyword> <Keyword>Sputtering deposition</Keyword> <Keyword>Cobalt alloys</Keyword> <Abstract>The IrMn/Py/Ru/Co (Py = Ni81Fe19) spin valves have been produced by sputtering deposition and analyzed by magnetization measurements and a theoretical modelling of their exchange interactions, based on the macro-spin model.
