act, new materials arc always one of crucial issues for the development of society. In 1940s, the thriving of semiconductors absolutely changed the woMINISTRY OF EDI CATION AND TRAINING HANOI UNIVERSITY OF SCIENCE AND TECHNOLOGYSchool of Engineering PhysicsMonte Carlo study of the room-temperature f Monte carlo study of the room temperature ferromagnetism of diluted magnetic semiconductor f materials named “diluted magnetic semiconductor” (DMS) has widely attracted interest. DMS combines properties of semiconductor and magnetic material in only one subject. Therefore, they are potential candidates for designing spintronics devices. DMS, firstly, was considered in 1960s which derived Monte carlo study of the room temperature ferromagnetism of diluted magnetic semiconductor from compound of Eu or composite compound in nature. However, posibility in application was restricted because of low Curie temperature phase transitiMonte carlo study of the room temperature ferromagnetism of diluted magnetic semiconductor
