Voltage control of ferromagnetic resonance and spin waves.

Ferromagnetic materials have a self-generating magnetic field, ferroelectric materials generate their own electrical field. Although electric and magnetic fields are related, physics tells us that. Such anomalous Dresselhaus-like spin current is further confirmed by the current-induced shift of the hysteresis loop when the magnetic field is swept along the current direction. However, when the ferromagnetic metal exhibits amorphous crystal structure or polycrystal structure, the Dresselhaus-like spin current is absent. Efficient spin/charge interconversion is desired to develop innovative spin-based devices. So far, the interconversion has been performed by using heavy atomic elements, strong spin-orbit interaction of which realizes the interconversion through the spin Hall effect and the Edelstein effect. We demonstrate highly efficient charge-to-spin conversion in a ferromagnetic metal/Cu/Al2O3 trilayers.

Band structure and spin texture of Bi2Se3 3d ferromagnetic metal interface.

Ferromagnetism. Iron, nickel, cobalt and some of the rare earths (gadolinium, dysprosium) exhibit a unique magnetic behavior which is called ferromagnetism because iron (ferrum in Latin) is the most common and most dramatic example. Samarium and neodymium in alloys with cobalt have been used to fabricate very strong rare-earth magnets. The magnetism in ferromagnetic materials is caused by the alignment patterns of their constituent atoms, which act as elementary electromagnets. Some species of atoms possess a magnetic moment; that is, such an atom itself is an elementary electromagnet produced by the motion of electrons about its nucleus and by the spin of those electrons.

In ferromagnetic substances, to the magnetic dipole moment of atoms, the contribution of the spin magnetic moment is very large. According to the domain theory, a ferromagnetic substance consists of a large number of small units (regions) known as Domains. Ferromagnetic materials have a strong attraction to applied magnetic fields and are able to retain their magnetic properties even after the field has been removed.
