All-optical control of the magnetization of polycrystalline exchange bias bilayer systems is achieved using short picosecond laser pulses. Due to the photoexcitation, the spin temperature across the interface between the ferromagnetic and antiferroma

A hot-spin and phonon gas in an exchange-biased metallic bilayer is induced by an 8.5-ps laser excitation. The spin-lattice temperature dynamics is sensed in real time by the time evolution of the exchange bias field on the picosecond time scale. A c

A three-layer sample of Fe(100 A)/Cr(0–20 A)/Fe(100 A) is used to study the dependence of inter-layer exchange on the thickness of the chrome interlayer and on temperature. The method of Kerr magnetometry in the temperature range from 77 to 473 K a

Ferromagnetic shape-memory alloys have recently emerged as a new class of active materials showing very large magnetic-field-induced extensional strains. Recently, a single crystal of a tetragonally distorted Heusler alloy in the NiMnGa system has sh

In order to study the role of the exchange interaction at and near the interface, Ni 81 Fe 19 /Fe 50 Mn 50 bilayers have been studied, which have an intervening layer of varying thickness and position in the antiferromagnetic Fe 50 Mn 50 layer. The r

The interlayer coupling in Fe/Cr/Fe layer system with wedge-type chromium spacers was investigated as a function of chromium thickness and temperature using Kerr magnetometry and Mandelstam–Brillouin light scattering techniques. The system with a m

We present a technique for broadband electrical characterization of nanowires up to 40 GHz. The technique relies on established on-wafer, microwave calibration methods as well as direct measurement of the capacitive coupling that is in parallel with

Small and large angle excitations in exchange bias systems have been investigated in real time by means of all-optical pump-probe experiments. Time resolved magneto-optics has been employed as a probe of the transient magnetic phenomena upon laser ex
