Underlying magnetization responses of magnetic nanoparticles in assemblies
Mohammad Reza Zamani Kouhpanji, Pieter B Visscher, Bethanie J H Stadler
Magnetic nanoparticles (MNPs) have been proposed as an ultimate solution for diverse applications including nanomedicine and logic devices over decades. However, none has emerged r…
MFM and FORC+ study of switching mechanism in CoPd films
Joseph. B. Abugri, Billy D. Clark, P. B. Visscher +2
Recent research on CoPd alloys with perpendicular magnetic anisotropy (PMA) has suggested that they might be useful as the pinning layer in CoFeB/MgO-based perpendicular magnetic t…
Avoiding the anomaly using FORC+ (expanded version of paper GG-05, MMM-Intermag 2019)
P. B. Visscher
In conventional FORC (First Order Reversal Curve) analysis of a magnetic system, reversible and low-coercivity irreversible materials are treated as being qualitatively different:…
FORC+ Analysis of Perpendicular Magnetic Tunnel Junctions
Joseph B. Abugri, P. B. Visscher, Subhadra Gupta +2
We have studied magnetic tunnel junction (MTJ) thin-film stacks using the First Order Reversal Curve (FORC) method. These have very sharp structures in the FORC distribution, unlik…
FORC+: A method for separating reversible from irreversible behavior using first order reversal curves
P. B. Visscher
First Order Reversal Curves (FORCs) have been used for a number of years for the extraction of information from magnetization measurements. The results are most unambiguous for irr…
Instability Mechanism for STT-MRAM switching
P. B. Visscher, Kamaram Munira, Robert J. Rosati
To optimize the design of STT-MRAM (spin-transfer torque magnetic random access memory), it is necessary to be able to predict switching (error) rates. For small elements, this can…
