Abstract
We present the first experimental observation of a spin reorientation phase transition (SRT) with the X-ray circular-magnetic-dichroism (XCM D) technique. The XCMD signal, related to the projection of the rare-e arth moment on the direction of the X-ray beam, has been measured as a function of temperature for both, a first-order SRT in Er2Fe14B (abru pt reorientation by 90-degrees) and a second-order one in Nd2Fe14B (co ntinuous tilt of the magnetization from the c-axis). The feasibility o f this technique to study SRTs and the capability to better understand the magnetic behaviour of intermetallic compounds exhibiting coexiste nce of itinerant and localized magnetism are demonstrated.
