Asymmetric spin-wave dispersion due to Dzyaloshinskii-Moriya interaction in an ultrathin Pt/CoFeB film
Kai Di, Vanessa Li Zhang, Hock Siah Lim +4
Employing Brillouin spectroscopy, strong interfacial Dzyaloshinskii-Moriya interactions have been observed in an ultrathin Pt/CoFeB film. Our micromagnetic simulations show that sp…
Determination of intrinsic spin Hall angle in Pt
Yi Wang, Praveen Deorani, Xuepeng Qiu +2
The spin Hall angle in Pt is evaluated in Pt/NiFe bilayers by spin torque ferromagnetic resonance (ST-FMR) measurements, and is found to increase with increasing the NiFe thickness…
Current-driven spin orbit field in LaAlO3/SrTiO3 heterostructures
Kulothungasagaran Narayanapillai, Kalon Gopinadhan, Xuepeng Qiu +4
We demonstrate a current tunable Rashba spin orbit interaction in LaAlO3/SrTiO3 (LAO/STO) quasi two dimensional electron gas (2DEG) system. Anisotropic magnetoresistance (AMR) meas…
Strain-enhanced tunneling magnetoresistance in MgO magnetic tunnel junctions
Li Ming Loong, Xuepeng Qiu, Zhi Peng Neo +5
While the effects of lattice mismatch-induced strain, mechanical strain, as well as the intrinsic strain of thin films are sometimes detrimental, resulting in mechanical deformatio…
Direct observation of the Dzyaloshinskii-Moriya interaction in a Pt/Co/Ni film
Kai Di, Vanessa Li Zhang, Hock Siah Lim +6
The interfacial Dzyaloshinskii-Moriya interaction (DMI) in an in-plane anisotropic Pt(4nm)/Co(1.6nm)/Ni(1.6nm) film has been directly observed by Brillouin spectroscopy. It is mani…
Thermally assisted domain wall nucleation in perpendicular anisotropy trilayer nanowires
Kulothungasagaran Narayanapillai, Xuepeng Qiu, Jan Rhensius +1
We study thermally assisted domain wall generation in perpendicular magnetic anisotropy CoFeB trilayer nanowires by the effect of Joule heating. The anomalous Hall effect is utiliz…
