Spin-valve effects in point contacts to exchange biased Co40Fe40B20 films
O. P. Balkashin, V. V. Fisun, L. Yu. Triputen +3
Nonlinear current-voltage characteristics and magnetoresistance of point contacts between a normal metal (N) and films of amorphous ferromagnet (F) Co40Fe40B20 of different thickne…
Spin Torques in Point Contacts to Exchange-Biased Ferromagnetic Films
I. K. Yanson, Yu. G. Naidyuk, O. P. Balkashin +6
Hysteretic magneto-resistance of point contacts formed between non-magnetic tips and single ferromagnetic films exchange-pinned by antiferromagnetic films is investigated. The anal…
Vortex-like state observed in ferromagnetic contacts
I. K. Yanson, Yu. G. Naidyuk, V. V. Fisun +4
Point-contacts (PC) offer a simple way to create high current densities, 10^9 A/cm^2 and beyond, without substantial Joule heating. We have shown recently (Nano Letters, 7 (2007) 9…
Current Driven tri-stable Resistance States in Magnetic Point Contacts
I. K. Yanson, V. V. Fisun, Yu. G. Naidyuk +4
Point contacts between normal and ferromagnetic metals are investigated using magneto-resistance and transport spectroscopy measurements combined with micromagnetic simulations. Pr…
Spin dynamics in point contacts to single ferromagnetic films
O. P. Balkashin, V. V. Fisun, I. K. Yanson +3
Excitation of magnons or spin-waves driven by nominally unpolarized transport currents in point contacts of normal and ferromagnetic metals is probed by irradiating the contacts wi…
Surface Spin-valve Effect
I. K. Yanson, Yu. G. Naidyuk, V. V. Fisun +4
We report an observation of spin-valve like hysteresis within a few atomic layers at a ferromagnetic interface. We use phonon spectroscopy of nanometer sized point contacts as an i…
