Geometry induced phase transitions in magnetic spherical shell
Equilibrium magnetization states in spherical shells of a magnetically soft ferromagnet form two out-of-surface vortices with codirectionally magnetized vortex cores at the sphere poles: (i) a whirligig state with the in-surface magnetization oriented along parallels is typical for thick shells; (ii) a three dimensional onion state with the in-surface meridional…
Magnetization in narrow ribbons: curvature effects
A ribbon is a surface swept out by a line segment turning as it moves along a central curve. For narrow magnetic ribbons, for which the length of the line segment is much less than the length of the curve, the anisotropy induced by the magnetostatic interaction is biaxial, with…
Magnonics and Magnonic Crystalls
When: Friday, May 10 at 12:20 Where: Faculty of Radio Physics, Electronics and Computer Systems What: Magnonics and Magnonic Crystalls Who: Anastasiia Korniienko Magnonics is the field of science referring to information transport and processing by spin waves. Magnons are the quanta of spin waves. They have advantages offering more efficient concepts for data transport and processing.…
