Nano-Contact Spin-Torque Oscillators as Magnonic Building Blocks the nano-contact with wavelength .=200–300 nm, decay length ..≈2 μm and group velocities ..≈3 μm/ns. We propose that the same type of NC-STOs can be used as spin wave manipulators, via control of the local Gilbert damping, and as spin wave detector using the spin torque diode effect.

0303-4216 inhas, Brazil.Magnonics is rapidly becoming a popular and ma.Spin waves (and their quanta magnons) can effectively carry and process information in magnetic nanostructures. By analogy to photonics, this research field is labelled magnonics. It comprises the study of excitation, detection, and manipu

Spin-Wave Eigen-modes in a Normally Magnetized Nano-pillar is performed by Magnetic Resonance Force Microscopy (MRFM). Distinct spectra are measured depending on whether the nano-pillar is excited by a uniform in-plane radio-frequency (RF) magnetic field or by an RF current flowing perpendicularly through the layers. These results are in agreement with mic

The Role of Angular Momentum in Ultrafast Magnetization Dynamics dynamics of angular momentum is considered in ferrimagnetic rare-earth–transition-metal alloys that consist of two antiferromagnetically coupled sublattices, where both magnetization and angular momenta are temperature dependent. For certain compositions, such ferrimagnets can exhibit a magnetizati

Probing Magnons by Spin-Polarized Electronslarized beam with a well-defined energy is scattered from the sample surface and the energy distribution of the scattered electrons is measured. Since magnons possess a total angular momentum of 1., they can only be excited (annihilated) by incidence of minority (majority) electrons. This fact leads

Micromagnetic Simulations in Magnonics– magnons. We argue that, when used with suitable post-processing tools, micromagnetics provide the power and flexibility necessary both for interpretation of complex magnonic phenomena observed in realistic magnetic structures and devices and for prediction of novel effects. We foresee that the dev
