Circular single domains in hemispherical small size Permalloy clusters
Clodoaldo I. L. de Araujo, Jakson M. Fonseca, João P. Sinnecker +3
We have studied ferromagnetic Permalloy clusters obtained by electrodeposition on n-type silicon. Magnetization measurements reveal hysteresis loops almost independent on temperatu…
Spin Transfer from a Ferromagnet into a Semiconductor through an Oxide barrier
C. I. L. de Araujo, M. A. Tumelero, A. D. C. Viegas +2
We present results on the magnetoresistance of the system Ni/Al203/n-doped Si/Al2O3/Ni in fabricated nanostructures. The results at temperature of 14K reveal a 75% magnetoresistanc…
Magnetoresistance in Thin Permalloy Film (10nm-thick and 30-200nm-wide) Nanocontacts Fabricated by e-Beam Lithography
Nicolas Garcia, Cheng Hao, Lu Yonghua +7
In this paper we show spin dependent transport experiments in nanoconstrictions ranging from 30 to 200nm. These nanoconstrictions were fabricated combining electron beam lithograph…
