Title: Induced antiferromagnetism in Mn doped BaMgF{sub 4}

Pure and Mn doped BaMgF{sub 4} samples have been synthesized by the hydrothermal method. X-ray diffraction (XRD) pattern of both the samples reveal the formation of pure BaMgF{sub 4} phase. High resolution scanning electron micrographs (HRSEM) show rectangular shape particles. At room temperature, the undoped BaMgF{sub 4} shows diamagnetic behavior where as the 5% Mn doped BaMgF{sub 4} exhibits antiferromagnetic hysteresis loop. The possible reason for room temperature antiferromagnetism and the role of dopant ion have been investigated.
