Target domains in nanometric Permalloy disks with columnar structure

Autor: Hélène Joisten, Svetlana Ponomareva, Philippe Sabon, Bernard Dieny, Robert Morel

We conducted a thorough experimental and numerical study of the micromagnetic properties of Permalloy (Ni$_{80}$Fe$_{20}$) microdisks exhibiting target domain structures at remanence. Vortex configurations are quite common in such microdisks and corr

International audience; Nano-patterning magnetic tunnel junction (MTJ) cells at low dimension and very dense pitch remains a challenge for high density STT-MRAM due to the difficulty of MTJ stacks etching. To circumvent this etching issue, this paper

A new kind of nanodevice that acts like tweezers through remote actuation by an external magnetic field is designed. Such device is meant to mechanically grab micrometric objects. The nanotweezers are built by using a top-down approach and are made o
