Abstract

The effects of diluting Gd with Y on the magnetic properties of the giant magnetocaloric effect material Gd ₅Si ₂Ge ₂ was investigated. It was observed that the dynamic response for Gd ₅Si ₂Ge ₂ at 15 and 150 K consists of two magnetic excitations extending up to 40 meV. Nearly 50 % reduction was showed in the ordering temperature of Gd ₅Si ₂Ge ₂. It was found that the observed magnetic dynamic response for the Gd ₄YSi _1.9Ge _2.1 was different from the nondiluted compound and the positions and intensities of the magnetic excitations changed with respect to Gd ₅Si ₂Ge ₂.
