Temperature-induced magnetization reversal in a YVO(sub3) single crystal
Article Abstract:
The application of a sufficiently large magnetic field in the opposite direction can reverse a magnetic moment, and such properties are the basis of magnetic recording and storage devices. However magnetization reversal responding to changes in temperature is quite rare and sometimes occurs in ferrimagnetic materials. Multiple temperature-induced magnetization reversals in YVO(sub3) were observed, with the magnetic moment due to V(super3+) ion tilting because of orthorhombic distortion.

High-transition-temperature superconductivity in the absence of the magnetic-resonance mode
Article Abstract:
The fundamental mechanism that gives rise to high-transition-temperature superconductivity in the copper oxide materials is discussed. Superconductivity is strong in terms of the transition temperature, which rule out the magnetic resonance peak and phonons as the principal cause of high transition temperature superconductivity.

Magnetic enhancement of superconductivity from elctron spin domains
Article Abstract:
The measurements of the heat capacity and magnetization, which show that for particular orientations of an external magnetic field, superconductivity in the heavy- fermion material is enhanced through the magnetic moments of individual electrons, are reported.
