The 3^rd Dvořák Lecture

Since their discovery in 1971 the superfluid phases of Helium-3 have proved to be the ideal testing ground for many fundamental concepts of modern physics.

Today, an important challenge in the field of spin based electronic devices is to manipulate the magnetization of a ferromagnetic layer without applying an external magnetic field in order to reduce energy consumption. Recently, a renewed attention has been paid to the magneto-electric effect, i.e. coupling between magnetization and electric polarization, in magnetic ferroelectric or multiferroic materials. A new concept of writing magnetic memories using multiferroic materials could be an interesting alternative to spin-transfer torque.
