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…
Magnetic relaxation in a model of interacting nanoparticles in terms of microscopic energy barriers
Oscar Iglesias, Amilcar Labarta
Monte Carlo simulations are used to study the magnetic relaxation of a system of single domain particles with dipolar interactions modeled by a chain of Heisenberg classical spins.…
