Magnetic phase diagram and critical behavior of Fe2As
Abstract
The magnetic-field temperature phase diagram and critical behavior of Fe2As are described. Spin-orientation changes with field are observed, in agreement with theoretical expectations, but tetracritical behavior is not found. A model based upon random strains is proposed to explain the failure to show the anticipated critical behavior. © 1981 The American Physical Society.
