Microscopic origin of exchange bias in core/shell nanoparticles
Oscar Iglesias, Xavier Batlle, Amilcar Labarta
We report the results of Monte Carlo simulations with the aim to clarify the microscopic origin of exchange bias in the magnetization hysteresis loops of a model of individual core…
From Finite-Size and Surface Effects to Glassy Behaviour in Ferrimagnetic Nanoparticles
Amilcar Labarta, Xavier Batlle, Oscar Iglesias
This chapter is aimed at studying the anomalous magnetic properties (glassy behaviour) observed at low temperatures in nanoparticles of ferrimagnetic oxides. This topic is discusse…
Loop Bifurcation and Magnetization Rotation in Exchange Biased Ni/FeF2
Justin Olamit, Elke Arenholz, Zhi-Pan Li +6
Exchange biased Ni/ FeF2 films have been investigated using vector coil vibrating sample magnetometry as a function of the cooling field strength H_FC. In films with epitaxial FeF2…
Bi-domain state in the exchange bias system FeF2/Ni
O. Petracic, Zhi-Pan Li, Igor V. Roshchin +4
Independently exchange biased subsystems can coexist in FeF2/Ni bilayers after various field-cooling protocols. We find double hysteresis loops for intermediate cooling fields, whi…
