Perpendicular magnetic anisotropy: from ultralow power spintronics to cancer therapy Most thin magnetic films have their magnetization lying in the plane of the film because of shape anisotropy. In recent years there has been a resurgence of interest in thin magnetic films which exhibit a magnetization easy axis along the surface normal due to so-called Perpendicular Magnetic Anisotropy (PMA). PMA has its origins in the symmetry breaking which occurs at surfaces and interfaces and can be strong enough to dominate the magnetic properties of some material systems.

“Magnetic and structural characterization of magnetic nanoparticles biosynthesized by magnetotactic bacteria”

LOURDES MARCANO

(UPV/EHU)

Magnetotactic bacteria are a microorganism that can align and navigate in geomagnetic fields thanks to the internal presence of a chain of magnetic nanoparticles, also called magnetosomes. These chains play the role of a compass needle and allow to the bacteria to orientate in the Earth´s magnetic field to find a more comfortable and richer in nutrients environment [1].
