Effect of Mn-site doping on the magnetotransport properties of the colossal magnetoresistance compound La2/3Ca1/3Mn1-xAxO3 (A=Co, Cr; x≤0.1)
(American Physical Society, 2000-09)
In this paper we show the effect of Mn site substitution (≤10%) by Co and Cr on the magnetotransport properties of ceramic samples of La2/3Ca1/3MnO3. Resistivity, magnetization, and magnetoresistance were systematically ...
Colossal anisotropy in diluted magnetic topological insulators
(2010)
We consider dilute magnetic doping in the surface of a three dimensional topological insulator
where a two dimensional Dirac electron gas resides. We find that exchange coupling between magnetic
atoms and the Dirac ...
Contactless measurement of colossal magnetoresistance in La1-xSrxMnO3 using the infrared magnetorefractive effect
(Elsevier B.V., 2004-05-01)
The magnetorefractive effect (MRE) has been used for the first time to study the magnetotransport properties of La1-xSrxMnO3 perovskite materials. A direct correlation between the MRE and colossal magnetoresistance was ...

Controlling the preferential orientation in sol-gel prepared CaCu3Ti4O12 thin films by LaAlO3 and NdGaO3 substrates
(Elsevier Science, 2016-11)
Researchers have paid considerable attention to CaCu3Ti4O12 (CCTO) due to the colossal dielectric constant over a wide range of frequency and temperature. Despite of the growing number of works dealing with CCTO, there ...
Partial preservation of chiral symmetry and colossal magnetoresistance in adatom-doped graphene
(American Physical Society, 2014-02-15)
We analyze the electronic properties of adatom-doped graphene in the low-impurity-concentration regime. We focus on the Anderson localized regime and calculate the localization length ξ as a function of the electron doping ...
Partial preservation of chiral symmetry and colossal magnetoresistance in adatom doped graphene
(American Physical Society, 2014-02)
We analyze the electronic properties of adatom-doped graphene in the low-impurity-concentration regime. We focus on the Anderson localized regime and calculate the localization length ξ as a function of the electron doping ...
Standard methods for Apis mellifera propolis research
(2016-09-29)
Propolis is one of the most fascinating honey bee (Apis mellifera L.) products. It is a plant derived product that bees produce from resins that they collect from different plant organs and with which they mix beeswax. ...
