Hydroxyapatite (HA) films have been widely recognized for their biocompatibility and utility in promoting biointegration of implants in both osseous and soft tissue. Conventional sputtering techniques have shown some advantages over the commercially available plasma spraying method; however, the as-sputtered films are usually amorphous which can cause some serious adhesion problems when post-deposition...
We have synthesized two new chalcopyrite compounds: MnGeP 2 and MnGeAs 2 . Total energy calculations predicted that both compounds are indirect semiconductors with band gaps of 0.24 and 0.06eV, respectively. Both compounds exhibit room-temperature ferromagnetism with T C ~320 and 340 K for MnGeP 2 and MnGeAs 2 , respectively, based on magnetization and resistance...
