Effects of deposition temperature on the structural, electrical and magnetic properties of Mn1.56Co0.96Ni0.48O4 spinel films grown on YSZ (100) substrates by pulsed laser deposition
摘要
Abstract
Mn1.56Co0.96Ni0.48O4(MCNO)thin films with spinel structure were grown on YSZ(100)substrates at different deposition temperatures from 500℃to 700℃by pulsed laser deposition.Since the deposition tempera-ture is an important factor in fabricating high-quality films,the structural,electrical and magnetic properties of MCNO thin films as a function of deposition temperature are investigated.By analyzing the X-ray diffraction pat-terns and the atomic force microscopy images,it is discovered that the crystallization of MCNO films is highly de-pendent on the deposition temperature.With the increasing deposition temperature,the resistivity of MCNO thin films is a change of V-type,and the electrical conduction of the MCNO films is controlled by a small polaron hop-ping mechanism.Meanwhile,the temperature-dependent magnetization curve reveals that all the samples show ferromagnetism to paramagnetism transition and the MCNO film deposited at 600℃has a high Curie temperature of 216 K.All the results above demonstrate that MCNO film deposited at 600 ℃ has satisfactory performance, which is desirable for applications of thermistor devices and multifunctional heterojunctions.关键词
