Low temperature spin reorientation in dysprosium iron garnet

Adsorbate and thermally induced spin reorientation transition in low-temperature-grown Fe/Cu(001)

Magnetic and Magneto-optic Study of a Layered Co/Pt - Dysprosium-Iron-Garnet System

We have studied the effects of placing Co/Pt multilayers on dysprosium-iron-garnet doped with bismuth and aluminum. The garnet was deposited by RF-magnetron sputtering and crystallized by rapid thermal annealing. The Co/Pt multilayers were then deposited by DC-magnetron sputtering. The garnet thickness was held constant at lOOOA while the ColPt multilayer had the form of [3ACo/9APt], with n ran...

Microscopic spin-wave theory for yttrium-iron garnet films

Motivated by recent experiments on thin films of the ferromagnetic insulator yttrium-iron garnet (YIG), we have developed an efficient microscopic approach to calculate the spin-wave spectra of these systems. We model the experimentally relevant magnon band of YIG using an effective quantum Heisenberg model on a cubic lattice with ferromagnetic nearest neighbour exchange and long-range dipole-d...

Spin-Wave Spectra of Yttrium and Gadolinium Iron Garnet

The problem of deducing the values of the exchange integrals in yttrium and gadolinium iron garnet from measurements of the magnetization and the magnetic contribution to the specific heat at low temperatures is considered. For these garnets the spin-wave normal modes can be found by solving the semiclassical equations of motion which give rise to a set of n simultaneous linear equations, where...

Generation of coherent spin-wave modes in yttrium iron garnet microdiscs by spin–orbit torque

In recent years, spin-orbit effects have been widely used to produce and detect spin currents in spintronic devices. The peculiar symmetry of the spin Hall effect allows creation of a spin accumulation at the interface between a metal with strong spin-orbit interaction and a magnetic insulator, which can lead to a net pure spin current flowing from the metal into the insulator. This spin curren...
