Graphene Overcoats for Ultra-High Storage Density Magnetic Media
N. Dwivedi, A. K. Ott, K. Sasikumar +10
Hard disk drives (HDDs) are used as secondary storage in a number of digital electronic devices owing to low cost (0.1$/GB at 2016 prices) and large data storage capacity (10TB…
Cloaking the magnons
Mehrdad Elyasi, Charanjit S. Bhatia, Cheng-Wei Qiu +1
We propose two approaches to cloak the spin waves (magnons) by investigating magnetization dynamics. One approach is based on a spatially inhomogeneous anisotropic magnetic moment…
Magnetization reversal using excitation of collective modes in nanodot matrices
Mehrdad Elyasi, Charanjit S. Bhatia, Hyunsoo Yang
The large arrays of magnetic dots are the building blocks of magnonic crystals and the emerging bit patterned media for future recording technology. In order to fully utilize the f…
Synchronization of spin-transfer torque oscillators by spin pumping, inverse spin Hall, and spin Hall effects
Mehrdad Elyasi, Charanjit S. Bhatia, Hyunsoo Yang
We have proposed a method to synchronize multiple spin-transfer torque oscillators based on spin pumping, inverse spin Hall, and spin Hall effects. The proposed oscillator system c…
Time-resolved imaging of pulse-induced magnetization reversal with a microwave assist field
Siddharth Rao, Jan Rhensius, Andre Bisig +5
The reversal of the magnetization under the influence of a field pulse has been previously predicted to be an incoherent process with several competing phenomena such as domain wal…
Strain-enhanced tunneling magnetoresistance in MgO magnetic tunnel junctions
Li Ming Loong, Xuepeng Qiu, Zhi Peng Neo +5
While the effects of lattice mismatch-induced strain, mechanical strain, as well as the intrinsic strain of thin films are sometimes detrimental, resulting in mechanical deformatio…
