Variable-range hopping conductivity in the copper-oxygen chains of La_3Sr_3Ca_8Cu_24O_41
T. Vuletic, B. Korin-Hamzic, S. Tomic +6
We show that the spin chain/ladder compound La_3Sr_3Ca_8Cu_24O_41 is an insulator with hopping transport along the chains. In the temperature range 35 - 280 K, DC conductivity sigm…
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…
High TC ferromagnetism in diluted magnetic semiconducting GaN:Mn films
H. Hori, S. Sonoda, T. Sasaki +4
Wurtzite GaN:Mn films on sapphire substrates were successfully grown by use of the molecular beam epitaxy (MBE) system. The film has an extremely high Curie temperature of around 9…
