In a radio communication system and radio communication apparatus, the ringing sound or melody of calling notification can be altered by users. A music data receiving section, a music data storage section and a music data reproducing section are provided within a controller. A calling party transmits a calling signal in which music data is appended to the message; a called party receives the calling signal through an antenna and radio section, where a music data receiving section is used to determine whether or not music data is contained in the received message in the calling signal, and, if it is contained, to perform ringing for calling notification with a speaker by using the music data.

An insulating composition consisting of Bi, Sr, RE, Cu, O or of Tl, Ba, RE, Cu, O (wherein; RE is an element selected from a group consisting of Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and Y) aligns properly with a crystal face of an oxide superconductor because its crystal structure is the same as or similar to that of the oxide superconductor. An insulating composition in which a part of Bi is replaced by Pb is further near the oxide superconductor its construction, and the modulation structure in this insulating composition is mitigated or disappears.

The magnetic field sensor is described for sensing the magnetic field, which comprises a light source part, a magnetic field detection part which contains a magnetooptic element consisting of a magnetic materials having a magnetooptic effect, and a light measurement part which measures the light that has been radiated from the light source part and has passed through the magnetic field detection part, is characterized in that the magnetooptic element is arranged such that its easy axis of magnetization is at substantially right angles to the direction of the magnetic field to be measured. The sensor can measure in a wide range of magnetic field with a high degree of accuracy and high sensitivity.

A process for producing a signal crystal of garnet ferrite comprises causing a signal crystal to grow by subjecting raw materials for the garnet ferrite to sintering so as to utilize the anomalous grain growth induced by the sintering. The process requires a shorter period of time for the growth of the single crystal, is free from mixing of impurities, and is capable of producing a single crystal with a high Faraday rotation while reducing production cost for the crystal.
