In this contribution we present the analysis of the third harmonic susceptibility data of the new superconductor NdFeAs1-0.14F 0.14. 'ColeCole' polar plots respect to the magnetic frequency of the exciting field are presented and discussed. Data show that NdFeAs 1-0.14F0.14 exhibit a 'bulk pinning' with a 3D flux dynamic character. A comparison of the responses of high Tc materials and an evaluation of theoretical critical states is also presented. © 2010 Elsevier Ltd.

Abstract
In this contribution we present the analysis of the third harmonic susceptibility data of the new superconductor NdFeAs1-0.14F 0.14. 'ColeCole' polar plots respect to the magnetic frequency of the exciting field are presented and discussed. Data show that NdFeAs 1-0.14F0.14 exhibit a 'bulk pinning' with a 3D flux dynamic character. A comparison of the responses of high Tc materials and an evaluation of theoretical critical states is also presented. © 2010 Elsevier Ltd.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
