Tailoring defects and nanocrystal transformation for optimal heating power in bimagnetic particles
George Antonaropoulos, Marianna Vasilakaki, Kalliopi N. Trohidou +5
The effects of cobalt incorporation in spherical heterostructured iron oxide nanocrystals (NCs) of sub-critical size have been explored by colloidal chemistry methods. Synchrotron…
Vacancy-driven non-cubic local structure and magnetic anisotropy tailoring in FeO-FeO nanocrystals
Alexandros Lappas, George Antonaropoulos, Konstantinos Brintakis +8
In contrast to bulk materials, nanoscale crystal growth is critically influenced by size- and shape-dependent properties. However, it is challenging to decipher how stoichiometry,…
Assembly-mediated Interplay of Dipolar Interactions and Surface Spin Disorder in Colloidal Maghemite Nanoclusters
A. Kostopoulou, K. Brintakis, M. Vasilakaki +5
Controlled assembly of single-crystal, colloidal maghemite nanoparticles is facilitated via a high-temperature polyol-based pathway. Structural characterization shows that size-tun…
Theory of ferromagnetism driven by superexchange in dilute magnetic semiconductors
C. Simserides, J. A. Majewski, K. N. Trohidou +1
Magnetic properties of GaMnN are studied theoretically by employing a tight binding approach to determine exchange integrals characterizing the coupling betwee…
Origin of low-temperature magnetic ordering in Ga1-xMnxN
M. Sawicki, T. Devillers, S. Gałȩski +9
By employing highly sensitive millikelvin SQUID magnetometry, the magnitude of the Curie temperature as a function of the Mn concentration x is determined for thoroughly characteri…
Ferromagnetic properties of p-(Cd,Mn)Te quantum wells: Interpretation of magneto-optical measurements by Monte Carlo simulations
A. Lipinska, C. Simserides, K. N. Trohidou +4
In order to single out dominant phenomena that account for carrier-controlled magnetism in p-(Cd,Mn)Te quantum wells we have carried out magneto-optical measurements and Monte Carl…
