Internal friction, crack length of fracture origin and fracture surface energy in alumina-zirconia composites
Two series of alumina-zirconia composites, i.e. alumina-unstabilized zirconia and alumina-partially stabilized zirconia with 3 mol % Y2O3, with different zirconia content were slip casted and fired at 1550°C for ...

Anisotropic Etching of Heavily Doped Polysilicon by a Hot Cl2 Molecular Beam
Anisotropic etching of n+ poly-Si is achieved using a hot Cl2 molecular beam and a sidewall protection technique. A hot molecular beam is produced by a free jet expansion of a gas heated in a furnace. A nitrogen ...

Interface reactions between glass melts containing transition metal oxides and ferrites
The interface reactions between SiO2-PbO-MO melts (M = Fe, Mn, Zn and Ni) and Mn-Zn and Ni-Zn ferrites were studied using electron probe microanalysis and X-ray diffraction. Ni ions in the glass melt containing N...

Observation of the intrinsic pinning of a magnetic domain wall in a ferromagnetic nanowire
Magnetic domain walls can be controlled through a spin torque, which is usually influenced by extrinsic factors, such as defects, that pin the domain walls to specific configurations. It is now shown that intr...

Electrical control of the ferromagnetic phase transition in cobalt at room temperature
The electrical control of magnetic properties is a key requirement for the development of spintronic devices. The demonstration that the ferromagnetic phase transition in cobalt can be changed by applying an e...

Direct visualization of the three-dimensional shape of skyrmion strings in a noncentrosymmetric magnet
Magnetic skyrmions are topologically stable swirling spin textures that appear as particle-like objects in two-dimensional (2D) systems. Here, utilizing scalar magnetic X-ray tomography under applied magnetic ...
