Electron Transport through Single Magnetic Molecules

Thermomagnetic studies on transition metal pnictides

The magnetocaloric effect (MCE) consists, in simple terms, in the heating of a magnetic material by the application of an external magnetic field. This can be easily understood if one but imagines a magnetic material with randomly applied spins; as a magnetic field is applied the spins will tend to alight with this field and as a result the...

Shape-induced ultrahigh magnetic anisotropy and ferromagnetic resonance frequency of micropatterned thin Permalloy films

Magnetic anisotropy Hk>200?Oe was observed from bar-shaped Permalloy strips. The film was deposited on sputtered Cr seed layer by electroplating under ? 800?Oe external magnetic field. Tiny degradation of Hk was observed after 30 min postannealing at 400?°C in the absence of external magnetic field. The Permalloy strip with in-plane aspect ratio...

Integrated Microstrip Lines With Co–Ta–Zr Magnetic Films

Magnetic properties of electroplated nano/microgranular NiFe thin films for rf application

A granular NiFe thin film with large in-plane magnetic anisotropy and high ferromagnetic-resonance frequency developed for radio-frequency integrated circuit (IC) applications is presented. During the deposition, three-dimensional (3D) growth occurs, yielding NiFe grains (? ? 1.0??m). Nanonuclei (? ? 30–50?nm) are observed in single NiFe grains...

Two-dimensional growth, anisotropic polaron transport, and magnetic phase segregation in epitaxial Nd0.52Sr0.48MnO3 films

Nd0.52Sr0.48MnO3 films have been fabricated by dc magnetron sputtering on single-crystal LaAlO3 (001) and SrTiO3 (011) substrates with additional annealing to relax the lattice strain. Although the Nd0.52Sr0.48MnO3 films were deposited simultaneously on different substrates at the same deposition rate, they differ in thickness by a factor of ? ....

Planar Hall effect and magnetic anisotropy in epitaxially strained chromium dioxide thin films

We have measured the in-plane anisotropic magnetoresistance of 100?nm thick CrO2 thin films at liquid He temperatures. In low magnetic fields H, both the longitudinal and the transverse (planar Hall) resistance show abrupt switches, which characteristically depend on the orientation of H. All the experimental findings consistently demonstrate...
