Abstract
DC magnetic susceptibility measurements as a function of temperature using the ZFC-FC protocol were performed in samples with xâ¯â¤â¯2/3. With the exception of xâ¯=â¯2/3, all samples show a similar behavior in the ZFC and FC curves which are typical of a system with a distribution of magnetic cluster sizes. Sample xâ¯=â¯2/3 shows ferromagnetic behavior with Tcâ¯=â¯50â¯K. For sample xâ¯=â¯1/4, measurements of the magnetization as a function of the applied magnetic field and temperature were performed. From the analysis of the curves it was found that the clusters contain 105 Ta-atoms and a coercitive field of 0.22â¯kOeâ¯atâ¯Tâ¯=â¯5â¯K.
