Investigations of the Magnetic Phase Transition in the LaFe_{11.14}Co_{0.66}Si_{1.1}M_{0.1} (Where M~=~Al or Ga) Alloys

Abstract

The aim of the present work was to study the phase transition in the LaFe11.14Co0.66Si1.1M0.1 (where M = Al or Ga) alloys. Research was carried out using field dependences of magnetization measured at a wide temperature range. Positive slope of the Arrott plots showed that magnetic phase transition in both investigated samples was of second order nature. The temperature dependences of the Landau coefficients also revealed second order phase transition in both specimens. The analysis carried out using universal curve confirmed second nature of phase transition in both samples.

The Microstructural Changes due to the Heating Treatment of Magnetic Amorphous Fe81(PtRh)5Zr7Nb1Cu1B5 Alloy

“…Such materials are obtained in the process of rapid solidification of the liquid alloy. This technique gives the possibility of obtaining tapes with a thickness of several dozen micrometers, tubes, plates or bars with a thickness of a few millimeters [1][2][3][4]. One of the many methods of obtaining classical crystalline alloys is the method consisting in rolling ingots and then subjecting them to heat treatment.…”
