Femtosecond laser pulses allow for extremely fast switching of magnetization in ferromagnetic films, but all examples so far contained gadolinium. Here the authors demonstrate room temperature all-optical toggle switching in a ferrimagnetic manganese

Compensated ferrimagnets are promising materials for fast spintronic applications based on domain-wall motion as they combine the favorable properties of ferromagnets and antiferromagnets. They inherit from antiferromagnets immunity to external field

Energy-efficient control of magnetization without the help of a magnetic field is a key goal of spintronics. Purely heat-induced single-pulse all-optical toggle switching has been demonstrated, but so far only in Gd-based amorphous ferrimagnet films.

The effect of vacuum annealing thin films of the compensated ferrimagnetic half-metal Mn $_{2}$ Ru $_{x}$ Ga at temperatures from 250 $^{\circ}$ C to 400 $^{\circ}$ C is investigated. The 39:3nm films deposited on (100) MgO substrates exhibit perpend

Silver nanoparticle films on glass and paper were prepared using vacuum pulsed laser deposition, and various methods of atmospheric pulsed laser deposition, where ablated material forms a nanoparticle aerosol near the target and is delivered in a gas

$\text{Mn}_{2}\text{Ru}_{\mathrm{x}}\text{Ga}$ (MRG) is a fully compensated half-metallic ferrimagnet [1]. We aim to engineer the position of the Fermi level in MRG thin films to modify the spin polarisation. Previous investigations of magnetoresista

We have a choice of methods for examining domains at the surface of a ferromagnet that depend on probing the stray field distribution, but these methods do not work in antiferromagnets or compensated ferrimagnets, which produce no stray field. The di

We report for the first time the observation of bunching of monoatomic steps on vicinal W(110) surfaces induced by step up or step down currents across the steps. Measurements reveal that the size scaling exponent {\gamma}, connecting the maximal slo
