Title: Effect of nickel substitution on magnetism in the layered van der Waals ferromagnet Fe 3GeTe 2

Abstract

We have grown a series of nickel-substituted single crystals of the layered ferromagnet (FM) Fe 3GeTe 2. The large single-crystalline samples of (Fe 1–xNi x) 3GeTe 2 with x = 0–0.84 were characterized with single-crystal x-ray diffraction, magnetic susceptibility, electrical resistance, and muon spin spectroscopy. We find Fe can be continuously substituted with Ni with only a minor structural variation. In addition, FM order is suppressed from T C = 212K for x = 0 down to T C = 50K for x=0.3, which is accompanied by a strong suppression of saturated and effective moments, and Curie-Weiss temperature. Beyond x=0.3, the FM order is continuously smeared into a FM cluster-glass phase, with a nearly full magnetic volume fraction. Here, we attribute the observed change in the nature of magnetic order to the intrinsically disordered structure of Fe 3GeTe 2 and subsequent dilution effects from the Ni substitution.
