Overview

What is he best known for?

The fields of study he is best known for:

  • Quantum mechanics
  • Condensed matter physics
  • Electron

Koki Takanashi spends much of his time researching Condensed matter physics, Magnetoresistance, Magnetic anisotropy, Ferromagnetism and Magnetization. Koki Takanashi works on Condensed matter physics which deals in particular with Quantum tunnelling. His Magnetoresistance study integrates concerns from other disciplines, such as Annealing, Metal and Superparamagnetism.

His biological study spans a wide range of topics, including X-ray crystallography, Monatomic ion, Superlattice and Lattice constant. In his work, Thermoelectric effect is strongly intertwined with Nernst effect, which is a subfield of Ferromagnetism. In his study, Microstructure, Magnetic domain, Sputtering, Single domain and Transmission electron microscopy is inextricably linked to Coercivity, which falls within the broad field of Magnetization.

His most cited work include:

  • Transmission of electrical signals by spin-wave interconversion in a magnetic insulator (979 citations)
  • ENHANCED MAGNETORESISTANCE IN INSULATING GRANULAR SYSTEMS : EVIDENCE FOR HIGHER-ORDER TUNNELING (284 citations)
  • Giant spin Hall effect in perpendicularly spin-polarized FePt/Au devices (282 citations)
