MICROWAVE DEVICES



Research team Microwave devices, within the Concepts group


On November, 20, we have the pleasure to welcome Romain Lebrun from University Johannes Gutenberg, Mainz, Germany. At 11H, room 434 A, he will present give a talk on “Mutual synchronization of spin torque nano-oscillators through a long-range and tunable electrical coupling scheme”. The concept of spin-torque-driven high-frequency magnetization dynamics, allows the potential construction of […]

Overview GREAT (European H2020 project) was accepted at the Summer 2015. Its kick-off meeting took place at SPINTEC in Grenoble on February 22nd-23rd 2016. The project aims at developing magnetic stacks able to equally perform memory, radio-frequency as well as sensor functionalities on the same chip, to address Internet of Things (IoT) applications. The main objectives of […]

Spin orbit effects

YIG delay lines: Description: Microwave wireless telecommunications are the backbone of the information age. They enable the exchange of data between connected objects. The Internet of Things is expected to connect as much as 80 billion objects by 2020. Accommodating such large number of handsets requires a paradigm shift in the performance of microwave analog […]

IMPEDANCE MATCHING

Increasing Output Power by impedance matching Description Impedance mismatch between the STNO device (for MTJs 100 – 1000 Ohm) and standard RF circuitry (at 50 Ohm) leads to a reduction of the output power of 10 dB. Proper impedance matching is thus important. Partners LETI/DCOS ; LETI/DACLE Financing ANR-05-NANO-44 MagICO (2005-2008) ; OSEO/Anvar (2005-2009) ; Carnot RF (2006-20010) ; […]

STNO DYNAMICS

Spin torque driven excitation spectra and microwave performances for different STNO configurations Description The dynamic response under spin transfer torque depends on the magnetization configuration of the polarizer and the free layer. At SPINTEC we have focused on two configurations which are (i) a perpendicular polarizer or (ii) a synthetic antiferromagnetic free layer. Partners LETI/DCOS […]

SPIN PUMPING

Injection and detection of pure spin currents using ferromagnetic resonance Description Damping enhancement in ferromagnetic resonance to study spin current injection from FM1 and spin absorption in FM2 or NM in magnetic heterostructures FM1/Cu/FM2 or FM1/Cu/NM. Partners Prof. W. E. Bailey, Columbia University, New York, USA F. Wilhelm, A. Rogalev, European Synchrotron Radiation Facility (ESRF), […]
