The Effects of Nickel Substitution on Ferromagnetism in Fe$_3$GeTe$_2$ Layered Structured Compound

ORAL

Abstract

We have grown a series of nickel substituted single crystals of the layered structured ferromagnet Fe$_3$GeTe$_2$. The crystals were characterized with single crystal X-ray diffraction, magnetic susceptibility, magnetization under pressure, electrical resistivity and Mossbauer spectroscopy. We will report the changes in the ferromagnetic transition temperature, ordered magnetic moment size, Curie-Weiss temperature and the crystallographic and magnetic structure, as a result of the nickel substitution.
