Interdependence between training and magnetization reversal in granular Co-CoO exchange bias systems
Menéndez Dalmau, Enric; Dias, Thiago; Geshev, Julian Penkov; López-Barberá Martín, José Francisco; Nogués Sanmiquel, Josep; Steitz, Roland; Kirby, Brian J.; Borchers, Julie A.; Pereira, Lino Miguel da Costa; Vantomme, A.; Temst, Kristiaan (2014) [Artículo de periódico]The interdependence between training and magnetization reversal in granular Co-CoO exchange bias (EB) systems prepared byOion implantation inCo thin films is demonstrated by polarized neutron reflectometry. While high-fluence ... -
Lift-off protocols for thin films for use in EXAFS experiments
Decoster, S.; Glover, C. J.; Johannessen, B.; Giulian, Raquel; Sprouster, David J.; Kluth, Patrick; Araújo, Leandro Langie; Hussain, Zohair S.; Schnohr, Claudia S.; Salama, H.; Kremer, Felipe; Temst, Kristiaan; Vantomme, A.; Ridgway, M.C. (2013) [Artículo de periódico]Lift-off protocols for thin films for improved extended X-ray absorption fine structure (EXAFS) measurements are presented. Using wet chemical etching of the substrate or the interlayer between the thin film and the ... -
Mossbauer study of the magnetic character and ordering process of the cubic gamma-fesi/sub 2/ phase obtained by fe implantation into a si(100) matrix
Maltez, Rogério Luis; Amaral, Livio; Behar, Moni; Vantomme, A.; Langouche, G.; Lin, X.W. (1996) [Artículo de periódico]The magnetic character and the ordering process of y-FeSi₂ precipitates formed by Fe implantation into Si(100) followed by ion-beam epitaxial crystallization (IBIEC) have been studied using the Mössbauer technique. ... -
Rotatable anisotropy driven training effects in exchange biased Co/CoO films
Dias, Thiago; Menéndez Dalmau, Enric; Liu, Haoliang; Van Haesendonck, Christian; Vantomme, A.; Temst, Kristiaan; Schmidt, Joao Edgar; Giulian, Raquel; Geshev, Julian Penkov (2014) [Artículo de periódico]The training effect for exchange bias in field-cooled Co/CoO bilayers films is investigated. Previous experiments on the same system have shown that, starting from the ascending branch of the first hysteresis loop, coherent ... -
Tuning the ferromagnetic-antiferromagnetic interfaces of granular Co-CoO exchange bias systems by annealing
Menéndez Dalmau, Enric; Modarresi, Hiwa; Dias, Thiago; Geshev, Julian Penkov; Pereira, Lino Miguel da Costa; Temst, Kristiaan; Vantomme, A. (2014) [Artículo de periódico]The low-temperature magnetic behavior of granular Co-CoO exchange bias systems, prepared by oxygen ion implantation in Co thin films and subsequent annealing, is addressed. The thermal activation effects lead to an O ...
