BT-7 Triple-Axis Summer School Experiment--2017
The Dynamics Summer School was held June 19 through June 23, 2017. The description of the experiment and data analysis that will be carried out for BT-7 spectrometer is: Colossal Magnetoresistive Spin Dyanmics. The introduction to the instrument is here.
To analyze the spin wave data we will use the SpinW program, and will also provide information on other programs that can be used.
We have also put together some examples of the types of data that can be obtained on BT-7, with brief explanations. Details can be obtained from the references. BT-7 examples.
