Metallic delafossite thin films for unique device applications
Takayuki Harada, Yoshinori Okada
Metallic delafossites (ABO2) are layered oxides with quasi-two dimensional conduction layers. Metallic delafossites are among the most conducting materials with the in-plane conduc…
Nonreciprocal transport in a Rashba ferromagnet, delafossite PdCoO
Jin Hong Lee, Takayuki Harada, Felix Trier +5
Rashba interfaces yield efficient spin-charge interconversion and give rise to nonreciprocal transport phenomena. Here, we report magnetotransport experiments in few-nanometer-thic…
Determination of the phase coherence length of PdCoO nanostructures
T. Harada, P. Bredol, H. Inoue +3
The two-dimensional layered compound PdCoO is one of the best oxide conductors, providing an intriguing research arena opened by the long mean free path and the very high mobil…
Anomalous Hall effect at the spontaneously electron-doped polar surface of PdCoO2 ultrathin films
T. Harada, K. Sugawara, K. Fujiwara +5
We revealed the electrical transport through surface ferromagnetic states of a nonmagnetic metal PdCoO2. Electronic reconstruction at the Pd-terminated surface of PdCoO2 induces St…
Highly conductive PdCoO2 ultrathin films for transparent electrodes
T. Harada, K. Fujiwara, A. Tsukazaki
We report on the successful synthesis of highly conductive PdCoO2 ultrathin films on Al2O3 (0001) by pulsed laser deposition. The thin films grow along the c-axis of the layered de…
Spin-filter tunnel junction with matched Fermi surfaces
T. Harada, I. Ohkubo, M. Lippmaa +5
Efficient injection of spin-polarized current into a semiconductor is a basic prerequisite for building semiconductor-based spintronic devices. Here, we use inelastic electron tunn…
