Experimental demonstration of complete 180 degree reversal of magnetization in isolated Co-nanomagnets on a PMN-PT substrate with voltage generated strain
Ayan Kumar Biswas, Hasnain Ahmad, Jayasimha Atulasimha +1
Rotating the magnetization of a shape anisotropic magnetostrictive nanomagnet with voltage-generated stress/strain dissipates much less energy than most other magnetization rotatio…
Image Processing with Dipole-Coupled Nanomagnets: Noise Suppression and Edge Enhancement Detection
Md Ahsanul Abeed, Ayan K. Biswas, Md Mamun Al-Rashid +2
Hardware based image processing offers speed and convenience not found in software-centric approaches. Here, we show theoretically that a two-dimensional periodic array of dipole-c…
Energy efficient and fast reversal of a fixed skyrmions with spin current assisted by voltage controlled magnetic anisotropy
Dhritiman Bhattacharya, Md. Mamun Al-Rashid, Jayasimha Atulasimha
Recent work [1,2] suggests that ferromagnetic reversal with spin transfer torque (STT) requires more current in a system in the presence of DMI than switching a typical ferromagnet…
Straintronic magneto-tunneling-junction based ternary content addressable memory
S. Dey Manasi, M. M. Al Rashid, J. Atulasimha +2
Straintronic magneto-tunneling junction (s-MTJ) switches, whose resistances are controlled with voltage-generated strain in the magnetostrictive free layer of the MTJ, are extremel…
Super-giant magnetoresistance at room-temperature in copper nanowires due to magnetic field modulation of potential barrier heights at nanowire-contact interfaces
