However, due to several intrinsic and extrinsic factors, these easy axes can be aligned away from the unidirectional axis. In this context, the aim of this work is to study the relationship between the easy axes distribution (EAD) and thickness of both the ferromagnetic (FM) and antiferromagnetic (AF) layers in Co/IrMn bilayer systems. A phenomenological model for the free energy of the system that takes into account a domain wall formation in the AF layer and a Gaussian-type distribution of their easy axes is used. Thus, we simulate and fit the magnetization curves and get several magnetic parameters like rotatable anisotropy field, exchange bias field, coercivity and magnetic anisotropy. Our results show that when the AF thickness is increased, the width of the easy-axis distribution also increases following a power-law relationship. However, no correlation is observed when the FM thickness is varied. Furthermore, considering an easy-axis distribution we observe a significant reduction in coercivity as well as a slight decrease of the exchange bias field.Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica - ConcytecengElsevier B.V.Physica B: Condensed Matterinfo:eu-repo/semantics/openAccessRotatable anisotropyAntiferromagnetism-1Coercive force-1Coercive force-1Domain walls-1Film growth-1Free energy-1Frequency modulation-1Antiferromagnetic grains-1Antiferromagnetic grains-1Domain wall formation-1Easy axis-1Exchange bias-1Magnetic field direction-1Magnetic field direction-1Phenomenological modeling-1Power law relationship-1Magnetic anisotropy-1https://purl.org/pe-repo/ocde/ford#1.03.00-1Thickness effect on the easy axis distribution in exchange biased Co/IrMn bilayersinfo: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##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#20.500.12390/806oai:repositorio.concytec.gob.pe:20.500.12390/8062024-05-30 15:22:59.756http://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##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#<Publication xmlns="https://www.openaire.eu/cerif-profile/1.1/" id="5d78e5e2-dd33-4155-a6f7-3bd01670f96f"> <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>Thickness effect on the easy axis distribution in exchange biased Co/IrMn bilayers</Title> <PublishedIn> <Publication> <Title>Physica B: Condensed Matter</Title> </Publication> </PublishedIn> <PublicationDate>2019</PublicationDate> <DOI>https://doi.org/10.1016/j.physb.2019.05.005</DOI> <SCP-Number>2-s2.0-85065698888</SCP-Number> <Authors> <Author> <DisplayName>Tarazona H.S.</DisplayName> <Person id="rp00839" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Tafur M.</DisplayName> <Person id="rp02068" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Quispe-Marcatoma J.</DisplayName> <Person id="rp01110" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Landauro C.V.</DisplayName> <Person id="rp00840" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Baggio-Saitovitch E.</DisplayName> <Person id="rp01241" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Schmool D.S.</DisplayName> <Person id="rp02069" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> </Authors> <Editors> </Editors> <Publishers> <Publisher> <DisplayName>Elsevier B.V.</DisplayName> <OrgUnit /> </Publisher> </Publishers> <Keyword>Rotatable anisotropy</Keyword> <Keyword>Antiferromagnetism</Keyword> <Keyword>Coercive force</Keyword> <Keyword>Coercive force</Keyword> <Keyword>Domain walls</Keyword> <Keyword>Film growth</Keyword> <Keyword>Free energy</Keyword> <Keyword>Frequency modulation</Keyword> <Keyword>Antiferromagnetic grains</Keyword> <Keyword>Antiferromagnetic grains</Keyword> <Keyword>Domain wall formation</Keyword> <Keyword>Easy axis</Keyword> <Keyword>Exchange bias</Keyword> <Keyword>Magnetic field direction</Keyword> <Keyword>Magnetic field direction</Keyword> <Keyword>Phenomenological modeling</Keyword> <Keyword>Power law relationship</Keyword> <Keyword>Magnetic anisotropy</Keyword> <Abstract>It is commonly assumed that in uncompensated FM/AF interfaces, the easy axes of antiferromagnetic grains are aligned toward the magnetic field direction applied during the film growth.
