    • The invention is related to a liquid nitrogen and liquid helium flow measurement chamber with optical window, developed in order to carry out measurements at low and high temperatures, compatible with measurement systems such as optical, magneto-optical, magneto-transport, microwave and magneto-caloric effect. The system enables to carry out measurements at high temperatures by means of the heater (6) that has been placed inside the nonmagnetic stainless steel holder (7) and besides this, it also enables to carry out measurements at low temperatures using liquid nitrogen and liquid helium by means of the liquid nitrogen and liquid helium transfer pipes (5). The system can be vacuumed up to ~10"6 mbar values by means of the vacuum connection pipe (14) and the vacuum cover (4) with optical window, during low temperature measurements. All of the connections that are used from the sample measurement location (8) to the contact connection station (9) for transport measurements, are controlled by means of a 19 pin connector (11).

    • The multi functional sample holder (6) and the high resolution detection system for Magneto optical Kerr effect measurements subject to the invention has been developed -in order to determine the magnetization curves of the samples (18) to be measured having magnetization at the sample plane and magnetization perpendicular to the sample plane. The system can be converted to Polar MOKE geometry from longitudinal MOKE geometry easily by means of the multi functional sample holder (6). Magnetization measurements depending on angle at the sample plane can be carried out by means of the stepper motor (7) which rotates the sample 360 degrees located in the multifunctional sample holder (6). Additionally high precision measurement results can be obtained even in samples with very weak magnetization by means of a filtering system using a lock-in amplifier (15).
    • 已经开发了多功能样品架(6)和本发明的用于磁光克尔效应测量的高分辨率检测系统,以便确定待测样品(18)的磁化曲线,其具有样品平面的磁化强度 和垂直于样品平面的磁化。 通过多功能样品架(6),系统可以轻松地从纵向MOKE几何转换为极地MOKE几何。 取决于样品平面处的角度的磁化测量可以通过使位于多功能样品架(6)中的样品360度旋转的步进电机(7)来执行。 另外,通过使用锁定放大器(15)的滤波系统,甚至可以获得具有非常弱的磁化的样本的高精度测量结果。
