Magnetic Properties of Amorphous Fe–Pd–B and Fe–Pt–B Alloys

The magnetic properties of amorphous Fe-Pd-B and Fe-Pt-B alloys are presented. The basis of our research were DTMD-DTA (derivative thermo-magnetogravimetry and differential thermal analysis) measurements, magnetic saturation measurements and low, ac field hysteresis loop measurements. The changes in the magnetic moment, Curie and crystallization temperature when Pt and Pd atoms substitute for Fe atoms are discussed. The most significant features of the hysteresis loop, such as the initial and maximum permeability, the saturation and remanence induction, the coercivity and the losses are presented.

Magnetic properties of metallic glasses based on Fe−Cr from Mössbauer spectroscopy

Spectra of metallic foils Fe80−xCrxB2 (x=6, 10, 15, 20) and Fe60Cr20B12Si8 were measured at range 4.2 K–300 K. Mössbauer data were analysed by Window’s Hesse-Rübartsch’s and Janot’s methods. The influence of the temperature and the Cr-content is discussed. The coefficientB3/2 in Bloch’s law was calculated. Curie and crystallization temperature were taken from the DTA-DTMG method [1]. For finding the Curie temperature of the sample Fe60Cr20B20 we used ac susceptibility, but this sample is not homogeneous.

Magnetic properties of amorphous alloys based on Fe depending on composition and temperature investigated by means of Mössbauer spectroscopy

Abstract The subject of our study is the dependence of the hyperfine magnetic field H in metallic amorphous alloys of the type Fe 80− x TM x B 20 (TM ≡ transition metal, x ≡ content of TM ) on the atomic number Z of TM and on temperature T . We us ed Mossbauer spectroscopy for these investigations. Mossbauer spectra were analysed by means of computer methods using Windows program. Over a half of these spectra were verified by using Hesse-Rubartschs program. The values obtained from these programs are consistent with a relative deviation of 2%. We also analysed the dependence of the dispersion ΔH of the hyperfine magnetic field distribution P(H) as a function of atomic number Z of TM. Some our results have been published, but now we present a full set of our results concerning metallic glasses of the type Fe-TM-B investigated by means of Mossbauer spectroscopy method.

Magnetic moment, Curie temperature and crystallization temperature of amorphous alloys of the type Fe-TM-B

Abstract There are presented magnetic properties of the metallic glasses of the type Fe 80−x TM x B 20 (TM: transition metal, x: at% of TM) as the magnetic moment, Curie temperature and also crystallization temperature depending on the atomic number Z of TM and on x . The problem of correlation between mean magnetic moment per Fe atom and hyperfine magnetic field is discussed.
