Magnetic vortex core observation in circular dots of permalloy
TL;DR: Experimental evidence for a spot of perpendicular magnetization at the center of the vortex is provided by magnetic force microscopy imaging of circular dots of permalloy (Ni(80)Fe(20)) 0.3 to 1 micrometer in diameter and 50 nanometers thick.
Journal ArticleDOI
Propagation of a magnetic domain wall in a submicrometer magnetic wire
TL;DR: The motion of a magneticdomain wall in a submicrometer magnetic wire was detected by use of the giant magnetoresistance effect and the propagation velocity of the magnetic domain wall was determined as a function of the applied magnetic field.
Journal ArticleDOI
Spin wave contributions to the high-frequency magnetic response of thin films obtained with inductive methods
TL;DR: In this paper, the high-frequency magnetic response of Permalloy thin films has been measured using network-analyzer ferromagnetic resonance, and it has been shown that the excitation of spin waves by the coplanar wave-guide modify the magnetic response appreciably, in particular, by causing a frequency shift and broadening of the resonance peak.
Journal ArticleDOI
MFM study of magnetic vortex cores in circular permalloy dots: behavior in external field
TL;DR: In this article, a vortex structure with turned-up magnetization at the core of a circular dot of permalloy with an appropriate size is realized, and the existence of the perpendicular magnetization spot has been confirmed and the direction of the magnetization, up or down, has been determined by magnetic force microscopy.
Journal ArticleDOI
Breaking of the C−C Bond of Cyclobutanones by Rhodium(I) and Its Extension to Catalytic Synthetic Reactions
TL;DR: In this article, a study of rhodium(I)-catalyzed synthetic transformations involving selective breaking of the C−C bond α to the carbonyl group of cyclobutanones is described.
