DC Magnetization study of Ni1-xRhx nanoalloy
Abstract
Ni1-xRhx bulk alloys exhibit a ferromagnetic to paramagnetic quantum phase transition (QPT) at the critical concentration xc 0.37. A spin glass phase arises below the Ferromagnetism by controlling the short range interaction between Ni and Rh atoms. we have synthesized nanoalloys of two different concentrations with two different reaction times by chemical reflux method. From the dc magnetization measurements, existence of ferromagnetism and spin glass phase in these nanoalloys is confirmed. A step like feature in both ZFC and FC curve at certain temperature indicates the existence of the spin glass phase.
