211. Theory of a magnetic microscope with nanometer resolution
Topic: Nanomagnetics
Published: 1/1/2001
Authors: P Johansson, S Apell, David R. Penn
Abstract: We propose a theory for a type of apertureless scanning near field microscopy that is intended to allow the measurement of magnetism on a nanometer length scale. A scanning tunneling microscope (STM) is used to scan a magnetic substrate while a laser ...

212. Tunneling Magnetoresistance With Amorphous Electrodes
Topic: Nanomagnetics
Published: 1/1/2007
Authors: M Gradhand, Christian Heiliger, P Zahn, I Mertig
Abstract: A detailed first principles analysis of the transport properties of different magnetic electrode materials for MgO tunnel junctions is performed to elucidate the microscopic origin of the TMR effect. The spin-dependent transport properties of the mag ...

213. Two Simple Tests for Models of Current-Induced Magnetization Switching
Topic: Nanomagnetics
Published: 1/1/2007
Authors: N Theodoropoulou, A Sharma, W Pratt, Mark D Stiles, J Xiao, J Bass
Abstract: We describe two simple tests for models of current-induced magnetization switching due to spin-transfer-torque in ferromagnetic/non-magnetic/ferromagnetic (F/N/F) trilayers. The first involves comparing calculated and measured values of the ratio X = ...

214. Two dimensional spectroscopic imaging of individual ferromagnetic nanostripes
Topic: Nanomagnetics
Published: 11/6/2012
Authors: Han-Jong H. Chia, Feng Guo, Lyubov Belova, Robert D McMichael
Abstract: We use ferromagnetic resonance force microscopy (FMRFM) to spectroscopically image the edge modes in individual 700 and 400 nm wide Permalloy stripes with a spatial resolution on the order of 200 nm. The imaging clearly identi es some resonances as ...

215. Vector Imaging of Magnetic Microstructure
Topic: Nanomagnetics
Published: 1/1/1989
Authors: Michael H Kelley, John Unguris, M Scheinfein, Daniel Thornton Pierce, Robert Celotta

216. What Can Polarized LEED Contribute to Surface Structure Determination?
Topic: Nanomagnetics
Published: 1/1/1984
Authors: Daniel Thornton Pierce, Robert Celotta, G Wang

217. Zigzag Shaped Magnetic Sensors
Topic: Nanomagnetics
Published: 1/1/2004
Authors: S da, Willard C Uhlig, A Kos, Jose Alberto Aumentado, Michael J Donahue, John Unguris, David P Pappas
Abstract: Magnetism in zigzag shaped thin film elements is investigated using scanning electron microscopy with polarization analysis, magneto-transport measurements, and micromagnetic simulations. We find that the angle of magnetization alternates along the l ...
