B111 強磁場を印加されたイオン結晶内のフオノン輸送(OS-6:マイクロ・ナノ熱工学(1))
詳細
The classical molecular dynamics simulation was carried out to study the effects of the strong magnetic field on the phonon transport properties of ionic crystals. Heat transport analysis for the alkali halide thin film model is conducted using nonequilibrium direct method. Strong magnetic flux density (〜10^6T) is applied perpendicularly to the direction of temperature bias. Thermal conductivity in the thickness direction decreases with increasing the magnetic flux density at low-temperature region (15K and 115K). In order to reveal the mechanism of change in thermal conductivity, spectral energy density (SED) is calculated and discussed.
