Sensitivity enhancement of an anomalous Hall effect magnetic sensor by means of second-order magnetic anisotropy
Hiroko Arai, Hiroshi Imamura
The sensing performance of anomalous Hall effect (AHE) magnetic sensors is investigated in terms of their sensitivity, the power spectrum of their voltage noise, and their detectiv…
1/f noise of a tiny tunnel magnetoresistance sensor originated from a wide distribution of bath correlation time
Hiroshi Imamura, Hiroko Arai, Rie Matsumoto +1
Tunnel magnetoresistance (TMR) sensor is a highly sensitive magnetic field sensor and is expected to be applied in various fields, such as magnetic recording, industrial sensing, a…
Critical current density of a spin-torque oscillator with an in-plane magnetized free layer and an out-of-plane magnetized polarizer
R. Matsumoto, H. Imamura
Spin-torque induced magnetization dynamics in a spin-torque oscillator with an in-plane (IP) magnetized free layer and an out-of-plane (OP) magnetized polarizer under IP shape-anis…
Resonant Magnetization Switching Conditions of an Exchange-coupled Bilayer under Spin Wave Excitation
W. Zhou, T. Yamaji, T. Seki +2
We systematically investigated the spin wave-assisted magnetization switching (SWAS) of a L10-FePt / Ni81Fe19 (Permalloy; Py) exchange-coupled bilayer using a pulse-like rf field (…
Theoretical analysis of the optimal conditions for photon-spin quantum state transfer
Y. Rikitake, H. Imamura, H. Kosaka
We analyzed the yield and fidelity of the quantum state transfer (QST) from a photon polarization qubit to an electron spin qubit in a spin-coherent photo detector consisting of a…
