Bi substituted Y- and Lu- iron garnets are very good materials for different kinds of magneto-optical applications. In this work we report the preparation of Bi,Ga: YIG and Bi,Ga: LuIG layers on Gd-Ga garnet (GGG) substrates grown by conventional, is

During the growth process of the Nd,Cr : Gd 3 Ga 5 O 12 (Nd,Cr : GGG) laser crystals the optimum concentrations of the dopants cannot be realized in axial direction of the crystal at a constant pulling (growth) rate as the effective segregation coeff

The temperature dependence of the domain-wall coercive field of epitaxial magnetic garnet films was modified in a defined temperature range by removing the surface layer of the films. Outside the given temperature range the coercivity versus temperat

The Nd:YVO 4 single crystal is one of the most promising laser hosts for micro and diode-pumped solid state lasers due to its outstanding laser characteristics. However, the growth difficulties encountered can significantly restrain its widespread hi

Several near quasicongruent undoped YVO4 single crystals grown by the Czochralski (CZ) technique as well as near stoichiometric YVO4 single crystals grown by the top‐seeded solution growth technique, were investigated by micro‐probe Raman spectro

Formation of a second magnetic layer was found in annealed epitaxial magnetic garnet film. The ratio of the layers is controlled by the annealing time. A linear relationship was found between the time of annealing and the thickness of the second laye

Aftereffect for magnetization processes by rotation and by domain wall motion was investigated on the same, single domain, two-state system of a square 2D (two-dimensional) array of garnet particles. Aftereffect measurements were performed magnetoopt

Due to the finite aspect ratio of the ferrite, the distribution of the internal field in small planar microwave ferrite devices is strongly inhomogeneous. This is a source of additional losses through magnetostatic modes. To study the magnetostatic m

For a nonellipsoidal magnetic sample, the internal magnetic field Hint(r) is inhomogeneous even when a uniform external magnetic field Happ is applied to it. In such a case the elements of the demagnetizing tensor become position‐dependent, N=N(r).

Thick, nominally pure (only lead substituted) Y3Fe5O12 (YIG) films have been grown on gadolinium gallium garnet (GGG) substrates 2 inches in diameter by isothermal dipping method of liquid phase epitaxy from lead-borate melt. If the liquidus temperat
