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…
Spin wave non-reciprocity and beating in permalloy by time-resolved magneto-optical Kerr effect
Siddharth Rao, Jungbum Yoon, Jan Rhensius +2
We have studied the propagation characteristics of spin wave modes in a permalloy stripe by time-resolved magneto-optical Kerr effect techniques. We observe a beating interference…
Electrical detection of microwave assisted magnetization reversal by spin pumping
Siddharth Rao, Sankha Subhra Mukherjee, Mehrdad Elyasi +2
Microwave assisted magnetization reversal has been investigated in a bilayer system of Pt/ferromagnet by detecting a change in the polarity of the spin pumping signal. The reversal…
Electric-field-induced magnetization changes in Co/Al2O3 granular multilayers
Ajeesh M. Sahadevan, Alan Kalitsov, Gopinadhan Kalon +3
We study experimentally the effect of electric field on the magnetization of Co/Al2O3 granular multilayers. We observe two distinct regimes: (a) low-field regime when the net magne…
Parallel-leaky capacitance equivalent circuit model for MgO magnetic tunnel junctions
Ajeesh M. Sahadevan, Kalon Gopinadhan, Charanjit S. Bhatia +1
The capacitance of MgO based magnetic tunnel junctions (MTJs) has been observed to be magnetic field dependent. We propose an equivalent circuit for the MTJs with a parallel-leaky…
