Unconventional GMR angular dependence using a compensated ferrimagnet
We have designed a GdCo/Cu/NiFe Giant Magnetoresistance (GMR) trilayer, the magnetoresistance of which does not always depend on the angle between the magnetisations of the electrodes. Using a GdCo ferrimagnetic alloy close to compensation, it was possible to experimentally reach the spin flop field Bsf of the ferrimagnetic layer. Below Bsf , the ferrimagnetic layer behaves as a ferromagnetic l...
متن کاملHalf-metallic ferrimagnet formed by substituting Fe for Mn in semiconductor MnTe
A ternary ferrimagnetic half-metal, constructed through substituting 25% Fe for Mn in zincblende semiconductor MnTe, is predicted in terms of accurate first-principles calculations. It has a large half-metallic (HM) gap of 0.54eV and its ferrimagnetic order is very stable against other magnetic fluctuations. The HM ferrimagnetism is formed because the complete moment compensation in the antifer...
متن کاملOrigin of metallic behavior in NiCo2O4 ferrimagnet
Predicting and understanding the cation distribution in spinels has been one of the most interesting problems in materials science. The present work investigates the effect of cation redistribution on the structural, electrical, optical and magnetic properties of mixed-valent inverse spinel NiCo2O4(NCO) thin films. It is observed that the films grown at low temperatures (T < 400 °C) exhibit met...
متن کاملDirac Half - Metal in a Triangular Ferrimagnet HIROAKI ISHIZUKA
Submitted for the MAR13 Meeting of The American Physical Society Dirac Half-Metal in a Triangular Ferrimagnet HIROAKI ISHIZUKA, YUKITOSHI MOTOME, Dept. of Appl. Phys., Univ. of Tokyo — Massless Dirac fermions show substantially different nature from ordinary electrons due to the peculiar cone-like dispersion with the point node. While it was originally introduced in the relativistic quantum the...
متن کاملHalf metallic ferromagnets.
Since its introduction by de Groot and colleagues in the early 1980s [1], the concept of half metallic ferromagnetism has attracted great interest. Idealized, half-metals have only one spin channel for conduction: the spin-polarized band structure exhibits metallic behavior for one spin channel, while the other spin band structure exhibits a gap at the Fermi level. Due to the gap for one spin d...
