Nanoscale stray fields from micromagnets for optimal spin qubit architecture
Sandrine Lopes, Quentin Schaeverbeke, Matthieu M. Desjardins +3
On-chip micromagnets generate local magnetic-field asymmetries, enabling electrical control of spin qubits via electric dipole spin resonance and their integration into circuit qua…
Hole transport across MgO-based magnetic tunnel junctions with high resistance-area product due to oxygen vacancies
F. Schleicher, B. Taudul, U. Halisdemir +13
The quantum mechanical tunnelling process conserves the quantum properties of the particle considered. As applied to solid-state tunnelling (SST), this physical law was verified, w…
Kinetic pathways to the magnetic charge crystal in artificial dipolar spin ice
I. A. Chioar, B. Canals, D. Lacour +6
We investigate experimentally magnetic frustration effects in thermally active artificial kagome spin ice. Starting from a paramagnetic state, the system is cooled down below the C…
Non-universality of artificial frustrated spin systems
I. A. Chioar, N. Rougemaille, A. Grimm +6
Magnetic frustration effects in artificial kagome arrays of nanomagnets with out-of-plane magnetization are investigated using Magnetic Force Microscopy and Monte Carlo simulations…
Energy levels of interacting curved nano-magnets in a frustrated geometry: increasing accuracy when using finite difference methods
H. Riahi, F. Montaigne, N. Rougemaille +3
The accuracy of finite difference methods is related to the mesh choice and cell size. Concerning the micromagnetism of nano-objects, we show here that discretization issues can dr…
Tunneling in double barrier junctions with 'hot spots'
D. Herranz, F. G. Aliev, C. Tiusan +3
We investigate electronic transport in epitaxial Fe(100)/MgO/Fe/MgO/Fe double magnetic tunnel junctions with soft barrier breakdown (hot spots). Specificity of these junctions are…
Artificial Kagome Arrays of Nanomagnets: A Frozen Dipolar Spin Ice
N. Rougemaille, F. Montaigne, B. Canals +8
Magnetic frustration effects in artificial kagome arrays of nanomagnets are investigated using x-ray photoemission electron microscopy and Monte Carlo simulations. Spin configurati…
