Time-resolved investigation of magnetization dynamics of arrays of non-ellipsoidal nanomagnets with a non-uniform ground state
P. S. Keatley, V. V. Kruglyak, A. Neudert +4
We have performed time-resolved scanning Kerr microscopy (TRSKM) measurements upon arrays of square ferromagnetic nano-elements of different size and for a range of bias fields. Th…
Current-driven microwave oscillations in current perpendicular-to-plane spin-valve nanopillars
Q. Mistral, Joo-Von Kim, T. Devolder +5
We study the current and temperature dependences of the microwave voltage emission of spin-valve nanopillars subjected to an in-plane magnetic field and a perpendicular-to-plane cu…
Angular Dependence of Spin-Torque Critical Currents in CPP-GMR Read Heads
Neil Smith, J. . A. Katine, Jeffrey R. Childress +1
This paper derives expressions for the critical current at the onset of spin-transfer-torque (STT) instability in CPP-GMR read heads, as a function of the relative angle (theta) be…
Thermal Effects on the Magnetic Field Dependence of Spin Transfer Induced Magnetization Reversal
D. Lacour, J. A. Katine, N. Smith +2
We have developed a self-aligned, high-yield process to fabricate CPP (current perpendicular to the plane) magnetic sensors of sub 100 nm dimensions. A pinned synthetic antiferroma…
Large-angle, gigahertz-rate random telegraph switching induced by spin-momentum transfer
Matthew R. Pufall, William H. Rippard, Shehzaad Kaka +4
We show that spin-polarized dc current passing through a small magnetic element induces two-state, random telegraph switching of the magnetization via the spin-momentum transfer ef…
Spin-Transfer Effects in Nanoscale Magnetic Tunnel Junctions
G. D. Fuchs, N. C. Emley, I. N. Krivorotov +7
We report measurements of magnetic switching and steady-state magnetic precession driven by spin-polarized currents in nanoscale magnetic tunnel junctions with low-resistance, < 5…
