Quantitative Studies of Spin-Momentum-Transfer-Induced Excitations in Co/Cu Multilayer Films Using Point-Contact Spectroscopy

February 24, 2003

Author(s)

William Rippard, Matthew Pufall, Thomas J. Silva

We have measured current-induced magnetic excitations in a variety of exchange-coupled Co/Cu multilayers using point-contact spectroscopy. A step in the DC resistance and corresponding peak in dV/dI are observed at a critical current Ic whose value

Detection of coherent and incoherent spin dynamics during the magnetic switching process using vector-resolved nonlinear magneto-optics

September 16, 2002

Author(s)

Thomas J. Silva, Pavel Kabos, Matthew Pufall

It is usually assumed that magnetic switching proceeds via coherent rotation under conditions of high symmetry. There is no a priori reason to expect an inhomogeneous response when a uniform magnetic torque is applied to a homogeneous ferromagnet. We test

Simultaneous measurement of surface and bulk vector magnetization dynamics in thin Ni-Fe films

February 1, 2002

Author(s)

Matthew Pufall, Thomas J. Silva

The dynamics of the surface and 'bulk' magnetization vectors of a Ni-Fe thin film were measured using the time-resolved second harmonic and linear magnetooptical Kerr effects. Films of 50, 250, and 400 nm thickness were measured. The magnetization dynamics

Design and performance of an inductive current probe for integration into the trace suspension assembly

January 1, 2002

Author(s)

Anthony B. Kos, Thomas J. Silva, Pavel Kabos, Matthew Pufall, Donald C. DeGroot, L Webb, M Even

A low-cost, inductive current probe designed for integration into a disk drive trace suspension assembly is described. The main consideration for this design was to use the same materials currently found in trace suspension assemblies, and thus reducing
