Room temperature superparamagnetism in amorphous Fe82Mn4B4Zr10 alloy
Source abstract
Abstract
Abstract Structural characterization and electron spin resonance study of amorphous Fe 82 Mn 4 B 4 Zr 10 ribbon with Curie temperature of 262 K is presented. According to X-ray diffraction analysis and transmission electron microscopy the alloy represents matrix with embedded micrograin heterogeneities, both existing in amorphous state. Size of the heterogeneities is about 50 nm, they show superparamagnetic state up to ∼500 K.
