Beschreibung
Zusammenfassung:	The invention belongs to the technical field of preparation of layered magnetic nano materials, and provides a preparation method of a two-dimensional FexGaTe (x = 2-5) magnetic crystal, which comprises the following steps of: placing a Fe source in a first corundum boat and arranged in a first temperature zone of a multi-temperature zone tube furnace, placing a Ga source and a Te source in a second corundum boat and arranged in a second temperature zone of the multi-temperature zone tube furnace, the two-dimensional FexGaTe (x = 2-5) magnetic crystal is prepared on the substrate in the second temperature zone through a chemical vapor deposition method, and in the reaction process, the temperature of the first temperature zone is 400-700 DEG C; the temperature of the second temperature zone is 500-900 DEG C; and the gas pressure intensity in the multi-temperature-zone tubular furnace is 10 to 100 kPa. According to the invention, a chemical vapor deposition method is developed to synthesize the two-dimensional
