Journal ArticleDOI
Excitation of a magnetic multilayer by an electric current
TL;DR: In this article, the authors proposed that the observed resistance changes are due to excitations of zero-wave-number spin waves in the magnetic layers, induced by a high current density injected into the multilayer through a point contact.
Journal ArticleDOI
Evidence for Two Superconducting Energy Gaps in MgB 2 by Point-Contact Spectroscopy
P. Szabó,P. Szabó,Peter Samuely,Jozef Kacmarcik,Thierry Klein,Jacques Marcus,Daniel Fruchart,Salvatore Miraglia,C. Marcenat,A. G. M. Jansen +9 more
TL;DR: Evidence is obtained for two distinct superconducting energy gaps in the multiband model of the superconductivity in the recently discovered system MgB(2) with the transition temperature T(c) = 39 K by means of Andreev reflection.
Journal ArticleDOI
Generation and detection of phase-coherent current-driven magnons in magnetic multilayers
TL;DR: The magnon spectrum is determined and how the magnon frequency and amplitude vary with the exciting current is investigated, supporting the feasibility of a spin-wave maser or ‘SWASER’ (spin-wave amplification by stimulated emission of radiation).
Journal ArticleDOI
Anisotropy of the upper critical field and critical current in single crystal MgB2
L. Lyard,L. Lyard,Peter Samuely,Pavol Szabó,Thierry Klein,C. Marcenat,L. Paulius,K. H. Kim,C. U. Jung,H. S. Lee,Byeongwon Kang,Seungje Choi,S.-I. Lee,J. Marcus,S. Blanchard,A. G. M. Jansen,Ulrich Welp,Goran Karapetrov,W. K. Kwok +18 more
TL;DR: In this paper, specific heat, high-magnetic field transport, and ac-susceptibility measurements on single crystals were reported on the entire temperature range, and a very different temperature dependence has been observed in the two directions, which yields a temperature-dependent anisotropy with a peak effect for H parallel to the c axis.
Journal ArticleDOI
Magnetoelectric properties of LiCoPO 4 and LiNiPO 4
Igor Kornev,Mirza Bichurin,Jean-Pierre Rivera,Sandrine Gentil,Hans Schmid,A. G. M. Jansen,P. Wyder +6 more
TL;DR: The magnetoelectric (ME) effect has been studied in detail near the N\'eel temperature as mentioned in this paper, where temperature hysteresis of the polarization induced by a magnetic field was found.
