電子的及び磁気特性のGaN / MNN / GaN及びMNN / GaN系/ MNN中間層

電子的及び磁気特性のGaN / MNN / GaN及びMNN / GaN系/ MNN中間層

本研究では、GaN / MNN / GaN及びMNN / GaN系/ MNN中間層の、構造的な電子的および磁気的特性を調査するために、計算の計算を実行します。 量子エスプレッソコードに実装された計算は、擬ポテンシャルに基づいた方法で行いました。 電子 - 電子相互作用の詳細については、一般化勾配近似（GGA）を使用しました。 総エネルギーの計算があることを明らかに GaN系/MNN / GaNの中間層は、精力的にそのMNN / GaN系/ MNN最も有利です。 状態密度の分析は、中間層は、Mn-D状態及びNpはフェルミ準位と交差ハイブリダイゼーション及び偏光から本質的に来る金属挙動を有することを示します。 中間層は8μβ/セルの磁気モーメントと磁気特性を持っています。 これらの特性により、 超格子 潜在スピントロニクスの分野で使用することができます。
