the performance of explored samples

For sampling for domain observations and their orientation the procedure of K.P.Belova of definition of standings of axes of easy magnetisation featured in chapter 2 and their temperature dependence by means of pseudo-free podvesa the sample in an orienting floor was used.

C the help of this device possible to find out trusty presence of anisotropy of the sixth order in a basic plane of hexagonal linking TbCo5 I (drawing 3.1), data about which in the literature were not given earlier.

Drawing 3.1 - Angular dependence of magnetisation in prismatic

Planes of monocrystal TbCo5д in an external field 0,5 T at T = 20, 60, 77, 83 and 118С.

In drawing 3.2 effects of magnetooptical definition of an interval of orientation transition by means of display ferrite-garnet of a film for a basic edge of spherical monocrystal DyCo52 are presented. Temperature dependence normal magnetisation builders was gained from computer measurings of contrast of magnetooptical images (drawing 3.3).

Drawing 3.2 - Temperature dependence of medial value of the module normal builders of a field near to a basic surface of monocrystal DyC05, gained from images of allocations fig. 3.3 (round points). Delta circuits - literary data.

From the presented data it is visible, that the magnetooptical procedure has given good coincidence to the literary data gained by a method of a magnetometer.
