Analytical Instruments
Holmarc has introduced a new innovative high sensitivity and high magnetic field Spectroscopic ellipsometric measuring equipment utilizing the VIS-NIR wavelengths. HOLMARC A216 test station provides standardized testing solution to fit wide ranging optical rotation measurement applications. The modular hardware design allows user to take automatic liquid, solid and thin film sample measurements under magnetic and no magnetic field.
Designed for magneto optic material research and testing including magnetic characterizations of ferromagnetic and ferrimagnetic films and materials. Measurement include magnetic hysteresis loops of ultrathin magnetic films and multilayers, Ellipticity measurements, Thin film thickness measurement of dielectric materials, Refractive index, Delta and psi measurements etc. System can be operated in Polar, Longitudinal and Transverse configurations.
Instrument is designed for measurement in the wavelength range of 380nm to 845nm using a high sensitive photo multiplier tube made by hamamatsu. It is an extremely flexible test station based on HARS. Any magnetic thin film, crystal or solutions having magnetic field dependancy can be measured.
It can be used to measure magnetic properties of magnetic thin films and nano-magnet arrays. Thin film thickness measurements under uniform magnetic field applied to the sample provides user to characterize each class of materials.
