Large magnetoresistance in intermetallic compounds R2Mn3Si5 (R = Tb, Dy and Ho)
R. Nirmala, S. K. Malik, A. V. Morozkin +2
Magnetization (M) and magnetoresistance (MR) measurements on polycrystalline R2Mn3Si5 (R = Tb, Dy and Ho) compounds (tetragonal, space group P4/mnc) have been carried out in the te…
Awaking of ferromagnetism in GaMnN through control of Mn valence
Saki Sonoda, Isao Tanaka, Fumiyasu Oba +10
Room temperature ferromagnetism of GaMnN thin films is awaked by a mild hydrogenation treatment of samples synthesized by molecular beam epitaxy. Local environment of Mn atoms is m…
Evidence for Carrier-Induced High-Tc Ferromagnetism in Mn-doped GaN film
S. Yoshii, S. Sonoda, T. Yamamoto +6
A GaN film doped with 8.2 % Mn was grown by the molecular-beam-epitaxy technique. Magnetization measurements show that this highly Mn-doped GaN film exhibits ferromagnetism above r…
Intrinsic mechanism for high temperature ferromagnetism in GaMnN
Saki Sonoda, Isao Tanaka, Hidekazu Ikeno +9
Considerable efforts have been devoted recently to synthesize diluted magnetic semiconductors having ferromagnetic properties at room temperature because of their technological imp…
Non-equilibrium and non-linear stationary state in thermoelectric materials
H. Iwasaki, M. Koyano, Y. Yamamura +1
Efficiency of thermoelectric materials is characterized by the figure of merit Z. Z has been believed to be a peculiar material constant. However, the accurate measurements in the…
Properties of Ferromagnetic Ga1-xMnxN Films Grown by Ammonia-MBE
Saki Sonoda, Hidenobu Hori, Yoshiyuki Yamamoto +5
Using ammonia as nitrogen source for molecular beam epitaxy, the GaN-based diluted magnetic semiconductor Ga1-xMnxN is successfully grown with Mn concentration up to x~6.8% and wit…
