Active Control of Mode Crossover and Mode Hopping of Spin Waves in a Ferromagnetic Antidot Lattice
Samiran Choudhury, Sudip Majumder, Saswati Barman +2
Active control of spin-wave dynamics is demonstrated using broadband ferromagnetic resonance in two-dimensional Ni80Fe20 antidot lattices arranged in hexagonal lattice with fixed l…
Tunable Angle Dependent Magnetization Dynamics in Ni80Fe20 Nano-cross Structures of Varying Size
Kartik Adhikari, Saswati Barman, Ruma Mandal +2
We demonstrate a large angular dependence of magnetization dynamics in Ni80Fe20 nano-cross arrays of varying sizes. By subtle variation of the azimuthal angle of an in-plane bias m…
Relation between spin Hall effect and anomalous Hall effect in 3 ferromagnetic metals
Yasutomo Omori, Edurne Sagasta, Yasuhiro Niimi +4
We study the mechanisms of the spin Hall effect (SHE) and anomalous Hall effect (AHE) in 3 ferromagnetic metals (Fe, Co, permalloy (NiFe; Py), and Ni) by varying t…
Anomalous Hall Effect in Thin Film of the Weyl Antiferromagnet MnSn
Tomoya Higo, Danru Qu, Yufan Li +3
The Weyl antiferromagnet MnSn has recently attracted significant attention as it exhibits various useful functions such as large anomalous Hall effect that are normally absent…
Phase Boundary Exchange Coupling in the Mixed Magnetic Phase Regime of a Pd-doped FeRh Epilayer
J. R. Massey, K. Matsumoto, M. Strungaru +8
Spin-wave resonance measurements were performed in the mixed magnetic phase regime of a Pd-doped FeRh epilayer that appears as the first-order ferromagnetic-antiferromagnetic phase…
Detection of the interfacial exchange field at a ferromagnetic insulator-nonmagnetic metal interface with pure spin currents
P. K. Muduli, M. Kimata, Y. Omori +3
At the interface between a nonmagnetic metal (NM) and a ferromagnetic insulator (FI) spin current can interact with the magnetization, leading to a modulation of the spin current.…
