The temperature and frequency dependent dielectric measurement is useful to understand the phase transitions of materials. This facility is developed in the Lab. of Multifunctional Materials at Department of Physics, Dr. B.R. Ambedkar National Institute of Technology, Jalandhar by Dr Kiran Singh, Assistant Professor and his Ph. D. student Ms. Vaidehi Deshmukh. The inauguration of this facility is done by Prof. L. K. Awasthi, Director, National Institute of Technology, Jalandhar. Dr. S. K. Mishra, Registrar, National Institute of Technology, Jalandhar, Prof. Arvinder Singh, Head Department of Physics, all faculty members and research scholar of Department of Physics were present on this occasion. Prof. L. K. Awasthi and Dr. S. K. Mishra congratulated Dr. Singh and research team for their efforts. Dr. Singh told that this development is the state of the art research facility under make in India initiative. This state of the art research facility is not available commercially. A home-made attachment is made to perform temperature dependent dielectric measurements at wide range of frequency (20 Hz- 300 kHz) and temperature (85-500 K) using Keysight LCR meter and Keithley digital multimeter. He also mentioned that all the necessary things like designing, connections etc. are made by us. The data acquisition software is developed in LabVIEW. This facility is useful to investigate the dielectric transitions in different types of samples like polycrystalline, thin film, single crystal and liquid crystals. This measurement facility is fully automated. The software is user friendly and all the required parameters can be controlled using the data acquisition software as per the user requirements. The measured parameters are plotted in real time and stored in the computer for later analysis. This facility is also suitable to perform such measurements down to 2 K and under high magnetic fields (0-140 kOe). These types of measurements will be useful to understand the phase transitions, dielectric relaxations and conduction mechanism of different materials. This facility is now open for the researchers of different academic/research institutes. Dr. Singh is very much thankful to Prof. L. K. Awasthi for his support and encouragement. The financial support for this development is provided by National Institute of Technology, Jalandhar and research project funded by UGC-DAE Consortium for Scientific Research, Indore. We are also thankful to UGC-DAE Consortium for Scientific Research, Indore for providing the financial support in the form of fellowship under CSR project.
