Autor: Jenichen, B, Takagaki, Y, Ploog, K H, Darowski, N, Feyerherm, R, Zizak, I

Publikováno v: Appl. Phys. Lett. 89, 051915 (2006)

The phase transition near 40~$^{\circ }$C of both as-grown thin epitaxial MnAs films prepared by molecular beam epitaxy on GaAs(001) and nanometer-scale disks fabricated from the same films is studied. The disks are found to exhibit a pronounced hyst

Characterization of L21 order in Co2FeSi thin films on GaAs

Autor: Jenichen, B, Hentschel, T, Herfort, J, Kong, X, Trampert, A, Zizak, I

Publikováno v: Journal of Physics: Conference Series 471 (2013) 012022

Co2FeSi/GaAs(110) and Co2FeSi/GaAs(-1-1-1)B hybrid structures were grown by molecular-beam epitaxy (MBE) and characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The films contain inhomogeneous distributions of ordered

Origin of the reduced exchange bias in epitaxial FeNi(111)/CoO(111) bilayer

Autor: Radu, F., Mishra, S. K., Zizak, I., Erko, A. I., Durr, H. A., Eberhardt, W., Nowak, G., Buschhorn, S., Zhernenkov, K., Wolff, M., Zabel, H., Schmitz, D., Schierle, E., Dudzik, E., Feyerherm, R.

Publikováno v: Phys. Rev. B 79, 184425 (2009)

We have employed Soft and Hard X-ray Resonant Magnetic Scattering and Polarised Neutron Diffraction to study the magnetic interface and the bulk antiferromagnetic domain state of the archetypal epitaxial Ni$_{81}$Fe$_{19}$(111)/CoO(111) exchange bias
