A study of the magnetotransport properties of the graphene (I. Monolayer) We present a single electron approach to analyse the magnetotransport properties of the monolayer graphene as a function of both, the gate voltage and the ... MA Hidalgo - 《Eprint Arxiv》 被引量: 2发表: 2014年 ...
- International Conference on Solid Compounds of Transition Elements 被引量: 0发表: 2017年 Quasispin Glass in a Geometrically Frustrated Magnet The spin glass state in the spinel ZnCr_(2(1-x))Ga_(2x)O_4 is studied with magnetization and specific heat for x < 0.05. The freezing ...
We investigated the magnetic properties of (La 1 − x Ba x )(Zn 1 − x Mn x )AsO with x varying from 0.005 to 0.05 at an external magnetic field of 1000 Oe. For doping levels of x ≤ 0.01, the system remains paramagnet
Recently, we have used melt-spinning to successfully synthesize hard magnetic nanocrystalline composite magnet materials based on SmFeCuGaC alloys having high coercivities up to 2.6 T [10]. We found that a small amount of Cu addition can significantly enhance the coercivity. However, the introducti...
The magnetic properties of $${\text{SrFe}}_{12}{\text{O}}_{19}$$ , a paradigmatic hexaferrite for permanent magnet applications, have been addressed in detail combining density functional theory including spin–orbit coupling and a Hubbard U term with Mo
In order to improve the magnetic properties of MnBi compound, anisotropic MnBi/Sm2Fe17Nx hybrid magnet was prepared by grinding of high purity MnBi ribbons and Sm2Fe17Nx particles together. The smooth hysteresis loops of the hybrid magnets indicated that the mixture of the hard/hard phase magneti...
Magnetotransport studies and mechanism of Ho- and Y-doped La0.7Ca0.3MnO3 Transport properties of mixed-valence manganites of the type (La0.7-xRx)Ca0.3MnO3 where R=Ho (magnetic) and Y (nonmagnetic) have been investigated above th... V.,Ravindranath,M.,... - 《Physical Review B》 被...
Most radicals may be considered to have arisen by cleavage of normal electron-pair bonds, every cleavage having produced two separate entities, each of which contains a single, unpaired electron from the broken bond (in addition to all the rest of the normal, paired electrons of the atoms). ...
The results of detailed study of the magnetotransport properties of broken-gap type II heterojunctions in a GaInAsSb/InAs(GaSb) system are reported. An electron channel with a high charge-carrier mobility (as high as 50000–60000 cm2/(V s)) is observed and studied for the first time in...
Indeed, the magnetisation of La3Ni2SbO9 increases markedly on cooling below 105 K and the ac susceptibility concomitantly becomes complex and frequency–dependent, as would be expected for a ferrimagnet. However, in contrast to LaSr2Cr2SbO9, no magnetic Bragg scattering was detected in a ...
