Instrument Description

The complex is used to study the elastic properties of liquids and solids, including the analysis of cell and tissue structures. Determination of microwave magnetization of samples is performed by scanning the sample with a laser beam on the surface in a magnetic field. Laser wavelength is 532 nm, power up to 200 mW. The scan area size is 100x100 microns in macro-BLS configuration and 50x50 mm in micro-BLS configuration, with positioning accuracy of 10x10 nm. Magnetic field range from 0 to 2 T with the possibility of reversing the electromagnet and controlled field magnitude change. Coherent excitation studies up to 20 GHz can be conducted with specially manufactured samples. Thermal magnon spectrum measurements are also possible, with an accuracy of up to 30 MHz.
