چکیده
We had found nonreciprocity of spin waves in Pt/Co/Ir/Co/Pt synthetic ferrimagnets by Brillouin light scattering technique. It is shown that the main contribution to made Dzyaloshinskii--Moriya interaction with an energy density D~ 1.7-2.3 erg/cm 2 . The Dzyaloshinsky--Moriya higher than its values heterostructures one Co layer Pt/Co(1 nm)/Ir ~1.4 D value decreases increasing thickness thin layer. Keywords: ferrimagnets, perpendicular magnetic anisotropy, scattering, exchange interaction,

Wide-Range Probing of Dzyaloshinskii–Moriya Interaction
The Dzyaloshinskii-Moriya interaction (DMI) in magnetic objects is of enormous interest, because it generates built-in chirality of magnetic domain walls (DWs) and topologically protected skyrmions, leading to efficient motion driven by spin-orbit torques. Because of its importance for both potential applications and fundamental research, many experimental efforts have been devoted to DMI inves...
متن کاملHund's Rule-Driven Dzyaloshinskii-Moriya Interaction at 3d-5d Interfaces.
Using relativistic first-principles calculations, we show that the chemical trend of the Dzyaloshinskii-Moriya interaction (DMI) in 3d-5d ultrathin films follows Hund's first rule with a tendency similar to their magnetic moments in either the unsupported 3d monolayers or 3d-5d interfaces. We demonstrate that, besides the spin-orbit coupling (SOC) effect in inversion asymmetric noncollinear mag...
متن کاملExchange bias driven by Dzyaloshinskii-Moriya interactions.
The exchange bias effect in a compensated IrMn3/Co(111) system is studied using multiscale modeling from ab initio to atomistic spin model calculations. We evaluate numerically the out-of-plane hysteresis loops of the bilayer for different thicknesses of the ferromagnetic layer. The results show the existence of a perpendicular exchange bias and an enhancement of the coercivity of the system. T...
متن کاملSimultaneous control of the Dzyaloshinskii-Moriya interaction and magnetic anisotropy in nanomagnetic trilayers.
Magneto-optical Kerr effect (MOKE) microscopy measurements of magnetic bubble domains demonstrate that Ar^{+} irradiation around 100 eV can tune the Dzyaloshinskii-Moriya interaction (DMI) in Pt/Co/Pt trilayers. Varying the irradiation energy and dose changes the DMI sign and magnitude separately from the magnetic anisotropy, allowing tuning of the DMI while holding the coercive field constant....
متن کاملDzyaloshinskii-Moriya interaction in the paramagnetic state and the polarized neutron scattering
Dzyaloshinskii-Moriya (DM) interaction in the paramagnetic state leads to the incommensurate spin fluctuations with incommensurate vector proportional to the relative strength of the DM interaction. We show that the DM interaction leads to helical spin fluctuations which may be observed by the polarized neutron scattering.
