VERITAS is a fixed-incident-energy triple-axis spectrometer that is most beneficial to the condensed matter physics and materials science research communities. It is an excellent instrument for measuring low-lying magnetic excitations in solids and for studying structural and magnetic phase transitions in bulk materials as well as thin films. Due to its versatility, this instrument can be used for parametric studies with a variety of sample environments to provide complete control of thermodynamic variables such as temperature, magnetic field, pressure, and electric field. VERITAS is a particularly good instrument for studying materials with weak scattering signals, including millimeter-size single crystals, powders, and thin films. The use of energy analysis in thin film studies is a key capability which enables the desired signal to be separated from the massive substrate background.
The following examples highlight the typical capabilities of HB-1A:
