Abstract

The series of Er2-xHoxFe14B (x = 0.5, 1.0, 1.5, 2.0) intermetallic compounds was studied in order to investigate different types of spin arrangements expected in this series. The variety of processes connected with spin reorientation, especially transition through conical spin arrangements was of special interest. The compounds have been measured with 57Fe Mössbauer spectroscopy over the temperature range 5.2-320 K. Each compound was studied with precise Mössbauer scanning in the vicinity of the transition. A special fitting procedure of Mössbauer spectra, enabling to analyze up to ten spectra simultaneously, was developed to determine the arrangement of spins. The path of spin rotation was proposed. The results were verified and compared by applying computer simulations based on the Yamada-Kato model. The spin arrangement diagram was constructed. Obtained results are convincing enough to conclude that Mössbauer spectroscopy can be very helpful in studies of tilt angle in conical spin arrangements in the studied type compounds.
