Controlling spin current polarization through non-collinear antiferromagnetism
T. Nan, C. X. Quintela, J. Irwin +20
The spin-Hall effect describes the interconversion of charge currents and spin currents, enabling highly efficient manipulation of magnetization for spintronics. Symmetry condition…
Materials Relevant to Realizing a Field-Effect Transistor based on Spin-Orbit Torques
Phillip Dang, Zexuan Zhang, Joseph Casamento +6
Spin-orbit torque is a promising mechanism for writing magnetic memories, while field-effect transistors are the gold-standard device for logic operation. The spin-orbit torque fie…
Imaging uncompensated moments and exchange-biased emergent ferromagnetism in FeRh thin films
Isaiah Gray, Gregory M. Stiehl, John T. Heron +5
Uncompensated moments in antiferromagnets are responsible for exchange bias in antiferromagnet/ferromagnet heterostructures; however, they are difficult to directly detect because…
Local Photothermal Control of Phase Transitions for On-demand Room-temperature Rewritable Magnetic Patterning
Antonio B. Mei, Isaiah Gray, Yongjian Tang +6
The ability to make controlled patterns of magnetic structures within a nonmagnetic background is essential for several types of existing and proposed technologies. Such patterns p…
Intrinsic nature of the giant spin Hall conductivity of Pt
Lijun Zhu, Lujun Zhu, Manling Sui +2
More than a decade after the first theoretical and experimental studies of the spin Hall conductivity (SHC) of Pt, both its dominant origin and amplitude remain in dispute. Resolvi…
Effective spin-mixing conductance of heavy-metal-ferromagnet interfaces
Lijun Zhu, Daniel C. Ralph, Robert A. Buhrman
The effective spin-mixing conductance (G_eff) of a heavy metal/ferromagnet (HM/FM) interface characterizes the efficiency of the interfacial spin transport.Accurately determining G…
