Magnetoresistive Sensor Detectivity: A Comparative Analysis
J. E. Davies, J. D. Watts, J. Novotny +2
We report on the noise performance characteristics of magnetic sensors using both magnetic tunnel junction (MTJ) and giant magnetoresistance (GMR) elements. Each sensor studied has…
Reconstructing phase-resolved hysteresis loops from first-order reversal curves
Dustin A. Gilbert, Peyton D. Murray, Julius De Rojas +3
The first order reversal curve (FORC) method is a magnetometry based technique used to capture nanoscale magnetic phase separation and interactions with macroscopic measurements us…
Effective anisotropy gradient in pressure graded [Co/Pd] multilayers
B. J. Kirby, P. K. Greene, B. B. Maranville +2
A vertically graded anisotropy profile has been proposed as an optimized balance of low coercivity and thermal stability for multilayers used in magnetic media. Deposition pressure…
Reversal mode instability and magnetoresistance in perpendicular (Co/Pd)/Cu/(Co/Ni) pseudo-spin-valves
J. E. Davies, D. A. Gilbert, S. M. Mohseni +3
We have observed distinct temperature-dependent magnetization reversal modes in a perpendicular (Co/Pd)4/Co/Cu/(Co/Ni)4/Co pseudo-spin-valve, which are correlated with spin-transpo…
The influence of structural disorder on magnetic domain formation in perpendicular anisotropy thin films
M. S. Pierce, J. E. Davies, J. J. Turner +10
Using a combination of resonant soft x-ray scattering, magnetometry, x-ray reflectivity and microscopy techniques we have investigated the magnetic properties and microstructure of…
Vertically Graded Anisotropy in Co/Pd Multilayers
B. J. Kirby, J. E. Davies, Kai Liu +5
Depth-grading of magnetic anisotropy in perpendicular magnetic media has been predicted to reduce the field required to write data without sacrificing thermal stability. To study t…
