Revealing Robust Room Temperature Ferromagnetism in Gd-Doped Few-Layered MoS₂ Thin Films.

ABSTRACT: 2D MoS₂ holds great promise for spintronics, yet is limited by intrinsic diamagnetism. This study demonstrates inducing ferromagnetic behavior in MoS₂ films doped with 0.47% Gd, achieving an ultrahigh saturation magnetization of 454 emu/cm³ in a few-layered film over 11-times higher than bulk films (40 nm). Raman spectroscopy, X-ray photoelectron spectroscopy, X-ray magnetic circular dichroism, and density functional theory (DFT) calculations reveal an interplay between Gd dopants and Mo, S vacancies (V_1Mo+2S), leading to the formation of bound magnetic polarons (BMPs) that drive ferromagnetic ordering. H₂S annealing and DFT calculations reveal that defect healing reduces the saturation magnetization by 83%. High sulfur migration barri
