Crystal-oriented (Li, Na, K) NbO3 ceramics (LNKN) were prepared by colloidal processing under a strong magnetic field, sintering, and subsequent electrical poling. The [001] direction of the LNKN particles with a tetragonal phase was oriented parallel to the magnetic field. By changing the direction of the magnetic field and machining, [001]-, [100]- and [110]-, and [101]-oriented LNKN powder compacts were formed. After phase transition during sintering, the crystal reorientation was furthermore enhanced by domain switching under an electric field. The obtained [001]-, [001]- and [101]-, and [101]-oriented LNKN ceramics showed piezoelectric constants d31 and d33 of 65 and 120 pm/V, 96 and 165 pm/V, 108 and 180 pm/V, respectively. In addition, d31 and d33 increased in the order of the [001]-, [001]- and [101]-, and [101]- oriented LNKN ceramics, indicating that the [101] orientation caused by domain switching is more effective for enhancing the piezoelectric properties compared to crystal orientation to the c-axis direction.

An unusual single-chain magnet (SCM), which is derived from a twisted arrangement of easy-planes of Fe(super II) along the chain axis, is reported and it generates a novel type of one-dimensional Ising system. An alternating Fe(super II) (high-spin)/Fe(super III) (low-spin) mixed valence single-chain magnet is prepared using a complexed ligand.

This article reports on an unusual single-chain magnet (SCM) formed by a twisted arrangement of ions with easy-plane magnetic anisotropy. The attention of nanoscientists is currently directed toward the behaviors of nanomagnets, such as single-molecule magnets and SCMs, since they show unique physical properties, such as quantum tunneling of magnetization and quantum phase interference, that are not observed in bulk magnets. An alternating Fe²/Fe³ mixed valence single-chain magnet was prepared using the complexed ligand. This twisting easy plane system is unique in that it exhibits easy-axis anisotropy over the whole chain, giving rise to stow magnetization reversal despite single ion anisotropy of the constituent Fe² ions with easy-plane.

In Japan, various types of MRI equipment, having varying magnetic field strengths, are widely used. However, the biggest problem encountered while utilizing an MRI is the scarcity of information and guidelines pertaining to implants, internal, and external metallic objects. This leads to uncertainty when an unspecified object is encountered during an examination andcreates the possibility of performing an ambiguous MRI. Therefore, this study classified a range of objects into 12 categories using database management software. An attempt was made to create an environment where reference and comparison of products could be performed. This study also investigated the ways and extent to which medical equipment package inserts reference the MRI. With the co-operation of various corporations and the use of information such as medical equipment package inserts, product information was collected and an environment for the reference and comparison of products became available. In addition, it became apparent while examining these package inserts that orthopedic products had the least information available. It is likely that this information will be useful in medical settings and this kind of database will become increasingly necessary in the future.
