ON THE NATURE OF THE HYSTERETIC BEHAVIOR IN GdCu COMPOUND

PDF Version Also Available for Download.

Description

Magnetic susceptibility measurements performed by de Wijn et al. were interpreted as to indicate the occurrence of a phase transformation from CsCl to the FeB structure in GdCu compounds at 77 K. The CaCl structure was found to reappear after a high temperature heat treatment. However, Ross et al. did not observe such a transformation by X-ray and Mossbauer effect measurements down to 4.2 K. A possible explanation for this disagreement was that the anomalous temperature dependence of the magnetic susceptibility of GdCu might be strongly dependent on the previous heat treatments of the compound. The objective of the present ... continued below

Description

Magnetic susceptibility measurements performed by de Wijn et al. were interpreted as to indicate the occurrence of a phase transformation from CsCl to the FeB structure in GdCu compounds at 77 K. The CaCl structure was found to reappear after a high temperature heat treatment. However, Ross et al. did not observe such a transformation by X-ray and Mossbauer effect measurements down to 4.2 K. A possible explanation for this disagreement was that the anomalous temperature dependence of the magnetic susceptibility of GdCu might be strongly dependent on the previous heat treatments of the compound. The objective of the present study was to investigate the behavior of the change in length and the electrical resistivity of GdCu over a wide temperature range in order to gain an insight into the reasons for the observed anomaly.
