Electronic and Magnetic materials are an active field of research due to their various applications ranging from memory and data storage to sensors and modulators. Manipulating phase transitions or magnetization using temperature, voltage, laser, strain forms the heart of these applications. We use X-ray techniques to image and understand the response of electronic and magnetic materials to the application of voltage, temperature and laser. Especially laser excitation allows us to reach femtosecond-nanosecond timescales, providing us with a unique method to image the phase transition or switching dynamics in these materials and manipulate physical properties on ultrafast timescales.
