초록

80-373 K의 온도범위에서 La$_{2.1}$ Sr$_{1.9}$ Mn$_3$O$_{10}$ 의 열기전력의 온도의존성을 조사하였다. 저온강자성영역에서 열기전력(S)의 온도의존성은 광범위한 온도영역에서 S=S$_{0}$ +S$_{1.5}$ T$^{1.5}$ +S$_4$T$^4$로 표현할 수 있었다. 강자성 전이온도 이하에서 열기전력의 완만한 피크 및 복잡한 온도의존성은 편력성 강자성체에서 예상되는 electron-magnon 산란으로 이해할 수 있으며, 고온에서의 열기전력은 Mott의 small polaron hopping 모델로 설명 가능하였다.

Temperature dependent thermoelectric power (TEP) of La$_{2.1}$ Sr$_{1.9}$ Mn$_3$O$_{10}$ system has been studied in the temperature range 80-373 K. In the low temperature ferromagnetic regime, TEP (S) follows an expression of formS=S$_{0}$ +S$_{1.5}$ T$^{1.5}$ +S$_4$T$^4$ over the wide range of temperature. The broad peak below the ferromagnetic transition and complicated temperature dependence of S may be understood on the basis of electron-magnon scattering as predicted for an itinerant ferromagnet. High temperature TEP data can be well fitted with Mott's small polaron hopping model.
