WebWe have studied the magneto-optic Kerr effect (MOKE) and static magnetic properties of MnGeAs2 films grown by using molecular beam epitaxy (MBE) and prepared in different arsenic ambiences. Both reflection high energy electron diffraction (RHEED) and 0-29 X-ray diffraction confirm epitaxial growth. WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We have synthesized two new chalcopyrite compounds: MnGeP2 and MnGeAs2. Total energy calculations predicted that both compounds are indirect semiconductors with band gaps of 0.24 and 0.06 eV, respectively. Both compounds exhibit room-temperature …
