Измерение МКЭ проводилось по методи

Измерение МКЭ проводилось по методике, описанной в […]. Для измерения МКЭ и магнитострикции использовался сверхпроводящая магнитная система на базе криокулера замкнутого цикла. Максимальное магнитное поле системы – 8 Тл. В сверхпроводящих соленоидах нельзя быстро менять ток для получения переменного магнитного поля. Для получения переменного поля использовался модуль линейного перемещения, который с заданной частотой вводит измерительную ячейку с образцом в магнитное поле и выводит его из поля.
Измерение теплового расширения и магнитострикции проводились тензометрическим методом. Измерения проводились как в постоянном поле, так и в переменном поле, причем при той же частоте, что и измерения МКЭ. Суть метода измерения магнитострикции в переменном поле заключается в следующем. Через тензометричесий мост пропускается постоянный ток, а образец вместе с приклеенным к нему тензодатчиком подвергается действию переменного магнитного поля, в полной аналогии с методом измерения МКЭ в переменном поле. Вследствие изменения размеров образца с изменением поля, на выходе тензометрического моста возникает переменный сигнал. Этот сигнал измеряется синхронным детектором. Таким образом, мы можем исследовать характер изменения параметров решетки при тех же самых условиях, при которых измеряется МКЭ. Это позволит определить магнитные и структурные вклады в общую величину МКЭ в данных материалах.

FEA measurement was carried out according to the technique described in [...]. For the measurement of magnetostriction and MEE used superconducting magnetic system based on closed-loop kriokulera. The maximum magnetic field system-8 TL. In superconducting solenoidah cannot quickly change current to obtain a variable magnetic field. To obtain the alternating fields used linear module, that introduces with a given frequency measuring cell with a model in a magnetic field and draws it from the field. Measurement of thermal expansion and magnetostriction method capable of being carried out. The measurements were carried out both in constant and alternating field, and with the same frequency that the FEM and measurement. The essence of the method of measurement of magnetostriction in an alternating field is as follows. Through tenzometričesij bridge skipped DC, and together with fixed thereto determined exposed to alternating magnetic field, in full analogy with the measurement method of the FEA in an alternating field. As a result of resizing the sample with the changing field, load cell/strain gauge bridge isolating alternating signal. This signal is measured by a synchronous detector. Thus, we can explore the nature of lattice parameter changes under the same conditions under which measured MEE. This will determine the magnetic and structural contributions to the total amount of ICE in these materials.

Measurement was conducted by the FEM method described in [...]. To measure the FEM and magnetostriction used a superconducting magnet system based on closed-cycle cryocooler. The maximum magnetic field of the system - 8 T. The superconducting solenoids can not quickly change the current for the alternating magnetic field. For the alternating field used linear motion module, which introduces a predetermined frequency measuring cell with the sample in a magnetic field, and removes it from the field.
Measurement of thermal expansion and magnetostriction were performed by the strain. Measurements were performed both in a static field and in an alternating field, and at the same frequency as the measurement of the FEM. The method of measurement of the magnetostriction in an alternating field is as follows. Through tenzometrichesy bridge passes a constant current, and a sample with him glued to the load cell is subjected to an alternating magnetic field, in complete analogy with the method of measuring the FEM in an alternating field. Due to changes in the size of the sample with the field, at the exit of the bridge there is a strain alternating signal. This signal is measured by a synchronous detector. Thus, we can explore the nature of the change in the lattice parameters under the same conditions under which the measured FEM. This allows to determine the magnetic and structural contributions to the total value MCE in these materials.

In the superconducting solenoids cannot be quickly to change current for the ac magnetic field.For ac fields used linear module, which at a specified rate enters the measuring cell with a model in a magnetic field and displays the from the field.
Measuring thermal expansion, and mathematics were a strain gauge load cell method. Measurements were made both in the constant field, and the alternating field, with the same frequency as vortexes and measurement.The method of measuring mathematics in alternating field is the following. Through тензометричесии axle passes constant current,A sample, together with glued to the тензодатчиком is subject to ac magnetic field, in full analogy with the method of measuring vortexes in alternating field.Because of changes in size sample with the change in the fields, at the outlet pointing stick caps axle there is a variable signal. This signal is measured synchronous detector. Thus,We can explore the nature of the changes to settings the grille under the same conditions, in which it is measured vortexes. This will enable you to determine magnetic and structural contributions to the overall value vortexes in the data material.
