Journal ArticleDOI
Spin-polarized tunneling in the half-metallic ferromagnets La 0.7-x Ho x Sr 0.3 MnO 3 (x=0 and 0.15): Experiment and theory
Pratap Raychaudhuri,K. Sheshadri,Praveen Taneja,S. Bandyopadhyay,Pushan Ayyub,A. K. Nigam,Reynaldo D. Pinto,Sujeet Chaudhary,S. B. Roy +8 more
TL;DR: In this paper, the authors derived a theoretical expression for the contribution of spin-polarized tunneling to the magnetoresistance in granular ferromagnetic systems under the mean-field approximation.
Journal ArticleDOI
Spin Wave Electromagnetic Nano‐Antenna Enabled by Tripartite Phonon‐Magnon‐Photon Coupling
TL;DR: In this paper , a tripartite coupling between phonons, magnons, and photons in a periodic array of elliptical magnetostrictive nanomagnets delineated on a piezoelectric substrate to form a 2D two-phase multiferroic crystal is investigated.
Journal ArticleDOI
Reflection and Refraction of a Spin at the Edge of a Quasi-Two-Dimensional Semiconductor Layer (Quantum Well) and a Topological Insulator
TL;DR: In this article , the reflection and refraction laws for an electron spin incident from a quasi-two-dimensional semiconductor region (with no spinorbit interaction) on the metallic surface of a topological insulator (TI) when the two media are in contact edge to edge.
Robustness of Binary Stochastic Neurons Implemented With Low Barrier Nanomagnets Made of Dilute Magnetic Semiconductors
Rahnuma Rahman,S. Bandyopadhyay +1 more
TL;DR: In this article , the authors show that if the nanomagnets are made of dilute magnetic semiconductors with much smaller saturation magnetization than common metallic ferromagnets, then the variability in their response times (due to shape variations and variation in the initial condition) is drastically suppressed.
Journal ArticleDOI
