The magneto-optic Kerr effect can probe the process of magnetization reversal in ferromagnetic thin films and can, thus, be used as an alternative to magnetometry. is wavelength-dependent rotation reverse sign, vanishing at particular wavelengths. We investigate epitaxial heterostructures manganite, La 0.7 Sr 0.3 Mn 0.9 Ru 0.1 O 3 , by using polar manganite layers are separated or interfaced wi...

Based on the data of thermogravimetric analysis values oxygen index (3-δ) in manganite La 0.7 Sr 0.3 Mn 0.9 Fe 0.1 O 3-δ composition, obtained by solid-phase reaction technique, have been calculated. The sorption-desorption curves showed that processes release and absorption at p 2 = 10 Pa 400 are not reversible. minima derivative dδ/d t f ( T ) corresponding to maxima extraction rate indicate ...

Comparison of a set perovskite electrodes shows that La1−x(Ca,Sr)xMnO3is critical to stabilize the ferroelectric orthorhombic phase in epitaxial films. The stabilization is favored if La content manganite high.

Magnetic refrigeration technology is a new, green, high-efficiency approach. It has attracted increasing attention from researchers and strong competitiveness over traditional methods. With the continuous development of social lives, magnetic must have important application prospects. This article briefly describes basic principles. The focus on introduction summary research perovskite manganit...

The hole-doped manganite La0.7Ca0.3MnO3 and the electron-doped manganite La0.7Ce0.3MnO3 undergo an insulator to metal transition at around 250 K, above which both behave as a polaronic semiconductor. We have successfully fabricated an epitaxial trilayer (La0.7Ca0.3MnO3/SrTiO3/La0.7Ce0.3MnO3), where SrTiO3 is an insulator. At room temperature, i.e. in the semiconducting regime, it exhibits asymm...
