- Effect of High Resistivity Phase on Low-Field Magnetoresistance of La2 . . .
The effect of YSZ doping level on transport properties and magnetoresistance in La2 3Ca1 3MnO3 has been experimentally studied The samples are prepared by a standard sol-gel method
- Effect of high resistivity phase on low-field magnetoresistance of La2 . . .
In this paper the influence of Fe doping at Co-site on the electrical transport properties and the colossal magnetoresistance of La0 67Sr0 33Co1−xFexO3 is studied The experimental results indicate
- Electrical transport and magnetoresistance in La2 3Ca1 3MnO3 BaZrO3 . . .
Remarkable changes of metal-to-insulator transition temperature, low-field magnetoresistance and high-temperature resistivity behavior were observed, suggesting importance of the variation of the manganite composition due to ionic interdiffusion in the La 2 3 Ca 1 3 MnO 3 BaZrO 3 composites
- Noise Probe of the Dynamic Phase Separation in La2 3Ca1 3MnO3
The effect of the field is to systematically stabilize the low-resistance state to the detriment of the high-resistance state Within the framework of the TLF model, the effect of the magnetic field can be accounted for by including a field-dependent energy barrier in Eq (1), FIG 2 (a) Schematic representation of an asymmetric double-
- Direct observation of oxygen vacancy-driven structural and resistive . . .
The accumulation of oxygen vacancies first changes the resistance by transforming LSMO into a mixed ionic-electronic conductor (high-resistance brownmillerite phase)
- Large, Controllable Spikes of Magnetoresistance in La2 3Ca1 3MnO3 . . .
The metal–insulator transition (MIT) has been observed around 140 K Below the MIT temperature, the superlattices have shown sharp drops of resistivity, facilitating the largest and sharpest magnetoresistance peaks (>2000%) ever observed in LCMO films and superlattices at low temperatures
- P Kharel and D J Sellmyer Hall effect in manganite thin films - IOPscience
Hall resistivity with I applied along [001] (a) and [110] (b) ¯ for a measurement under a saturating magnetic field, its amplitude being dependent on the temperature and on the direction of the electric current
- Effect of High Resistivity Phase on the Electrical Transport Properties . . .
Meanwhile, the resistivity with the content thereof is increased rapidly increases, especially associated with the grain boundary of the low-temperature resistivity In particular, we observed in the sample to a wide range of temperatures significantly enhanced the magnetoresistance effect
- (PDF) Kerr and Magnetorefractive Effects in La-Ca-MnO3 Superlattices
Magneto-optical Faraday and Kerr effects are associated with the rotation of the polarization plane of a polarized light transmitted or reflected from a magnetic media under application of magnetic field (H) These effects reach a maximum in saturating magnetic fields at temperatures significantly below the Curie temperature TC
- Magneto Transport of high TCR (temperature coefficient of resistance . . .
The temperature coefficient of resistance (TCR) near ferromagnetic (FM) transition is increased significantly with addition of Ag The FM transition temperature (TFM) is also increased slightly with Ag addition
