Exchange interactions in rare earth—transition metal compounds
TL;DR: In this paper, the R-T exchange-coupling parameter (ART) in RmTn (R = rare earth, T = Co or Fe, m/ n = 1 2 ; 1 3 ; 6 23 ; 1 5 ; 2 17 ; 1 12 ) and Rm TnBk (m / n / k = 1/4/1; 2/14/1, 1/12/6) systems has been evaluated from analyses of Curie temperatures.
Journal ArticleDOI
The magnetic behaviour of rare-earth—transition metal compounds
TL;DR: In this article, the basic exchange interactions for a variety of (R, T) compounds, in particular RT 2 (R: rare earth, or Y; T: transition metal), were discussed.
Journal ArticleDOI

TL;DR: In this paper, a single phase sample of standard garnet cubic structure was obtained after sintering the gel at 800 °C for 2 h and the hysteresis loop was measured at temperatures between 5 and 560  K and in applied magnetic fields up to 20 kOe.
Journal ArticleDOI
Crystallization and magnetic behavior of nanosized nickel ferrite prepared by citrate precursor method
TL;DR: In this paper, NiFe2O4 nanoparticles have been synthesized by citrate precursor gel formation with subsequent heat treatment and differential thermal and thermogravimetric (DTA/TG) analyses show that the metal citrates decomposed around 230 ◦C followed by crystallization of the ferrite.
Journal ArticleDOI
Key step in the synthesis of ultrafine strontium ferrite powders (SrFe12O19) by sol–gel method
TL;DR: In this paper, the magnetic properties and structure of strontium hexaferrite powders were studied at various ranges of calcination temperature (Tca) (750-900°C), calcination time (3min-2h), Fe/Sr molar ratios (RM) (10.5-12), and pH (1-8).
