Abstract

The Magneto-Optical Spectra and Behaviour of the Joint Density of States of the Intermetallic Compounds RFeZ (R = Gd, Tb, Dy, Ho, Er) andYFe2 BY K.M. MUKIMOV, SH.M. SHARIPOV, and L.A. ERNAZAROVA The properties of the cubic Laves phase RMZ intermetallic compounds (R: rare-earth, M: 3d transition metal) have been extensively studied for a long

“…Among them, the rare-earth Fe 2 (RFe 2 ) intermetallic compounds have been attractive for their high Curie temperatures and the simple cubic Lavesphase (C15) crystal structure. Katayama et al 1 measured the Kerr rotations of polycrystalline RFe 2 (RϭGd,Er,Ho,Dy, and Tb͒ using a null-type automatic Kerr spectrometer at room temperature with an applied magnetic field of 1.2 T. Mukimov et al 2 measured the magneto-optical equatorial spectra of polycrystalline RFe 2 (RϭGd, Tb, and Er͒ prepared by arc melting. From these, they derived the offdiagonal optical conductivities for GdFe 2 , TbFe 2 , and ErFe 2 .…”

MAGNETO-OPTICAL PROPERTIES OF AMORPHOUS RE-FeCo ALLOYS

“…The magneto-optical activity of magnetic materials usually originates from typical electronic transitions in a certain wavelength range as it is observed from crystalline alloys [1,2]. However, for amorphous alloys the spectral dependences of eK and eF show almost no structure due to the absence of a well defined band structure.…”

Critical Systematic Evaluation and Thermodynamic Optimization of the Fe-RE System: RE = Gd, Tb, Dy, Ho, Er, Tm, Lu, and Y

“…An eutectic reaction between Gdrich phase and GdFe 2 was also reported at 0.72 mol fraction Gd (X Gd ) and 830 ± 7°C. Later, Savitskii [46] reported four intermetallic phases Gd 2 Fe 17 , GdFe 4 , GdFe 3 , and GdFe 2 where all showed peritectic melting behaviors. In the review by Kubaschewski, [42] the phase diagram of the Fe-Gd system was proposed based on the experimental results of Copeland et al [44] with the modification of peritectic melting of Gd 6 Fe 23 based on Savitskii et al [46] and Burov et al [48] Most recently, Atiq et al [49] investigated the phase transformations in the Fe-rich side (less than 0.32 X Gd ) which were determined by DTA and diffusion couple technique.…”

“…Compounds of heavy-RE elements with other metals like Co, Fe, Ni etc. have unique properties of optical, [1] magnetic, [2] magnetocaloric effect, [3][4][5] magnetostriction [6] and electrical conductivity, [7] and electrocatalytic properties. [8,9] These properties make them valuable to the electronic, appliance, green technology, weapon and medical device manufacturing industry.…”
