Crossover From Individual to Collective Magnetism in Dense Nanoparticle Systems: Local Anisotropy Versus Dipolar Interactions
Elena H. Sánchez, Marianna Vasilakaki, Su Seong Lee +11
Dense systems of magnetic nanoparticles may exhibit dipolar collective behavior. However, two fundamental questions remain unsolved: i) whether the transition temperature may be af…
High temperature magnetic stabilization of cobalt nanoparticles by an antiferromagnetic proximity effect
Jose A. De Toro, Daniel P. Marques, Pablo Muniz +4
Thermal activation tends to destroy the magnetic stability of small magnetic nanoparticles, with crucial implications in ultra-high density recording among other applications. Here…
New Reversal Mode in Exchange Coupled Antiferromagnetic/Ferromagnetic Disks: Distorted Viscous Vortex
Dustin A. Gilbert, Li Ye, Aïda Varea +10
Magnetic vortices have generated intense interest in recent years due to their unique reversal mechanisms, fascinating topological properties, and exciting potential applications.…
Applications of exchange coupled bi-magnetic hard/soft and soft/hard magnetic core/shell nanoparticles
A. López-Ortega, M. Estrader, G. Salazar-Alvarez +2
The applications of exchange coupled bi-magnetic hard/soft and soft/hard ferromagnetic core/shell nanoparticles are reviewed. After a brief description of the main synthesis approa…
Pseudo Spin Valves Using a (112)-textured DO_22 MnGa Fixed Layer
C. L. Zha, R. K. Dumas, J. Persson +3
We demonstrate pseudo spin valves with a (112)-textured DO_22 MnGa (MnGa) tilted magnetization fixed layer and an in-plane CoFe free layer. Single D0_22 MnGa films exhibit a small…
High and low-temperature crystal and magnetic structures of epsilon-Fe2O3 and their correlation to its magnetic properties
M. Gich, C. Frontera, A. Roig +10
The crystal and magnetic structures of the orthorhombic e-Fe2O3 have been studied by simultaneous Rietveld refinement of X-ray and neutron powder diffraction data in combination wi…
Strong temperature dependence of antiferromagnetic coupling in CoFeB/Ru/CoFeB
N. Wiese, T. Dimopoulos, M. Rührig +4
The temperature dependence of saturation and spin-flop fields for artificial ferrimagnets (AFi) based on antiparallel coupled CoFeB/Ru/CoFeB trilayers has been investigated in a te…
