Sub-Wavelength Terahertz Spin-Flip Laser Based on a Magnetic Point-Contact Array
R. I. Shekhter, A. M. Kadigrobov, M. Jonson +3
We present a novel design for a single-mode, truly sub-wavelength THz disk laser based on a nano-composite gain medium comprising an array of metal/ferromagnetic point contacts emb…
Stimulated emission and absorption of photons in magnetic point contacts: toward metal-based spin-lasers
Yu. G. Naidyuk, O. P. Balkashin, V. V. Fisun +8
Point contacts between high anisotropy ferromagnetic SmCo5 and normal metal Cu are used to achieve a strong spin-population inversion in the contact core. Subjected to microwave ir…
Spin-thermo-electronic oscillator based on inverse giant magnetoresistance
A. M. Kadigrobov, S. Andersson, Hee Chul Park +4
A spin-thermo-electronic valve with the free layer of exchange-spring type and inverse magnetoresistance is investigated. The structure has S-shaped current-voltage characteristics…
Hot electrons in magnetic point contacts as a photon source
A. M. Kadigrobov, R. I. Shekhter, S. I. Kulinich +7
We propose to use a point contact between a ferromagnetic and a normal metal in the presence of a magnetic field for creating a large inverted spin-population of hot electrons in t…
