The calibration of the velocity scale of a Mossbauer spectrum using a standard absorber is approximated by a non-linear velocity-to-channel function. In case of triangular or sinusoidal mode, the full (i.e., unfolded) spectrum is evaluated. The non-l

The multilayer of approximate structure MgO(100)/[nFe51Rh49(63 Å)/57Fe51Rh49(46 Å)]10 deposited at 200 °C is primarily of paramagnetic A1 phase and is fully converted to the magnetic B2 phase by annealing at 300 °C for 60 min. Subsequent irradiat

The effect of selfabsorption in Mossbauer sources is studied in detail. Spectra were measured using an old 57Co/Rh source of 74MBq activity with an original activity of ca. 3.7GBq and a 0.15GBq57Co/α − Fe source magnetized by an in-plane magnetic

Electric field controlled ion transport and interface formation of iron thin films on a BaTiO3 substrate have been investigated by in situ nuclear resonance scattering and x-ray reflectometry techniques. At early stage of deposition, an iron-II oxide

A novel approach of determining the sign of the hyperfine magnetic field using elliptically polarized resonant γ-photons is presented. The method is demonstrated by a transmission experiment on α-Fe using a 57Co:α-Fe source partially saturated par

A 20 × [Fe(20 A)/Cr (12 A)]/MgO structure excited by an ultrasonic wave was investigated by polarized neutron reflectometry. It was found that magnetic domains oscillate and their effective size decreases in weak magnetic fields. In close-to-saturat
