摘要： PURPOSE:To obtain the titled single crystal having excellent light transmittance, and uniform light-transmission characteristics throughout nearly the whole length of the obtained single crystal, by adding a bivalent ion of Ca, Zn or Pb to a YIG composition. CONSTITUTION:A composition composed mainly of yttrium-iron garnet, is doped with a bivalent ion of Ca, Zn or Pb. The concentration of the dopant is 0.1X 10 -3.5X10 for Ca and 0.1X10 -2.8X10 for Zn and Pb. The above composition is converted to a single crystal by the travelling solvent floating zone process to obtain the desired YIG single crystal for optical communication.

摘要： PURPOSE:To enable the mass production of a titled single crystal having excellent characteristics of magnetic resonance, by incorporating a specified mol ratio of Ca ions in a composition consisting essentially of yttrium-iron garnet, and converting the obtained composition into a single crystal by a prescribed method. CONSTITUTION:Ca ions are adjusted so as to contain 0.4X10 -5.2X10 by mol ratio in a composition consisting essentially of yttrium-iron garnet and the mixed composition is converted into a single crystal by a traveling solvent floating zone method. YIG single crystals for microwave which have a small half- value width of magnetic resonance and are uniform almost all over the crystal can be mass-produced. Even though any one of divalent Zn or Pb is incorporated in 0.3X10 -4.4X10 by mol ratio instead of Ca ions, the single crystal having similar characteristics of magnetic resonance is obtd.

摘要： PURPOSE:To diminish the half-value width in the magnetic resonance of a spherically worked element in spherical working of a single crystal of ferrite by dipping the single crystal into a strong acid and etching the surface prior to finish polishing. CONSTITUTION:A single crystal of ferrite having a three-dimensional shape is worked roughly spherically and is controlled of the shape and size of the sphere in spherical working of a microwave nuclear magnetic resonance element. The single crystal is then dipped for about 30-50min at a suitable temp. in a hydrochloric acid or a strong acid consisting essentially of a hydrochloric acid to etch the surface, thereby relieving work strain. The half-value width in magnetic resonance is made much smaller by the above-mentioned method and the performance of a microwave oscillator and filter is improved.

摘要： PURPOSE:To reduce the magnetic resonance half width of a ferrite single crystal by surface-polishing a spherical sample while providing an impeller wheel made of a polisher material inside a vessel lined with the polisher material and allowing soft polishing powder to be contained in the polisher material. CONSTITUTION:An impeller wheel 17 made of a polisher material is rotatably provided within a vessel 10 lined with the polisher material 16, and soft polishing powder is stuck to said polisher material. The several number of spherical sample of a ferrite single crystal are uniformly put into each compartment formed by blades 17, and the impeller wheel 17 is rotated via a pulley 32. It is possible in this way to remove the surface over which the processing distortion on the spherical sample is formed and improve magnetic resonance half width to about 1.6 Oe.
